data sheet adum6210/adum6211/adum6212 rev. 0 | page 19 of 24 applications informa tion the dc - to - dc converter section of the adum6210 / adum6211 / adum6212 works on principles that are common to most modern power supplies. it ha s a s plit controller architecture with isolated pulse - width modulation (pwm) feed back. v ddp power is s upplied to an oscillating circuit that switches current into a chip - scale air core transformer. power transferred to the secondary side is rectified and regulated to a value between 3.15 v and 5.25 v depending on the set point supplied by an external voltag e divider (s ee equation 1 ) . the secondary (v iso ) side controller regulates the output by creating a pwm control signal that is sent to the primary (v ddp ) side by a dedicated i coupler data channel. the pwm modulates the oscillator circuit to control the pow er being sent to the secondary side. feedback allows for significantly higher power and efficiency. r1 r2 r1 v iso ) ( v 25 . 1 + = (1) w here: r1 is a resistor between v sel and gnd iso . r2 is a resistor between v sel and v iso . because the output voltage can be adjus ted continuously , there are an infinite number of operating conditions. this data sheet addresses three discrete operating conditions in the specifications tables. many other combinations of input and output voltage are possible ; figure 15 depicts the supported voltage combinations at room temperature. figure 15 was generated by fixing the v iso load and decreasing the input voltage until the pwm w as at 80% duty cycle . each of the curves represents the minimum input voltage that is required for operation under this criterion. for example, if the applica - tion requires 30 ma of output current at 5 v, the minimum input voltage at v ddp is 4.25 v. figure 15 also illustrates why the v ddp = 3.3 v input and v iso = 5 v configuration is not recommended. even at 10 ma of output current, the pwm cannot maintain less than 80% duty factor, leaving no margin to support load or temperatur e variations. typically, the adum6210 / adum6211 / adum6212 dissipates about 17% more power between room temperature and maxi - mum temperature; therefore, the 20% pwm m argin covers temperature variations. the adum6210 / adum6211 / adum6212 implement undervoltage lockout (uvlo) with hysteresis on the primary and secondary side i/o pins as well as the v ddp power input . this feature ensures that the converter does not go into oscillation due to noisy input power or slow power - on ramp rates. pcb layout the adum6210 / adum6211 / adum6212 digital isolators with 0. 1 5 w iso power integrated dc - to - dc converters require no exter - nal interface circuitry for the logic in terfaces. power supply bypass ing with a low esr capacitor is required , as close to the chip pa ds as possible . the iso power inputs require several passive components to bypass the power effectively as well as set the output voltage and bypass the core voltage regulator (see figure 24 through figure 26) . pwr en v ddp gnd p 10 f 0.1 f + 8 9 10 1 1042-022 figure 24 . v ddp bias and bypass components v sel v iso gnd iso 10 f 0.1 f + r1 10k ? r2 30k ? 13 12 11 1 1042-023 figure 25 . v iso bias and bypass components the power supply section of the adum6210 / adum6211 / adum6212 uses a 125 mhz oscillator frequency to efficiently pass power through its chip - scale transformers . bypass capaci - tors are required for several operating frequencies. noise suppression requires a low inductance, hig h frequency capacitor; ripple suppression and proper regulation require a large value bulk capacitor. these capacitor s are most conveniently connected between pin 9 and pin 10 for v ddp and between pin 11 and pin 12 for v iso . to suppress noise and reduce r ipple, a parallel combination of at least two capacitors is required. the recommended capacitor values are 0.1 f and 10 f for v dd1 . the smaller capacitor must have a low esr; for example, use of an npo or x5r ceramic capacitor is advised. ceramic capacit ors are also recommended for the 10 f bulk capacitance . an additional 10 nf capacitor can be added in parallel if further emi reduction is required. note that the total lead length between the ends of the low esr capacitor and the input pow er supply pin must not exceed 2 mm. gnd iso v se l pdis v dd p v iso gnd p by p ass < 2mm gnd iso adum6210/ adum6211/ adum6212 gnd p v ib /v ob v ia /v oa v ob /v ib v oa /v ia v dd1 v dd2 gnd p gnd iso 1 1042-024 figure 26 . recommended pcb layout in applications involving high common - mode transients, ensure that board coupling across the isolation barrier is minimized. furthermore, design the board layout such that any coupling that does occur equally affects all pins on a given component side. failure to ensure this can cause voltage differentials between pins, exceeding the absolute maximum ratings specified in table 19 , thereby leading to latch - up and/or perm anent damage.
adum6210/adum6211/adum6212 data sheet rev. 0 | page 20 of 24 thermal analysis the adum6210 / adum6211/ adum6212 consist of four internal die attached to a split lead frame with two die attach paddles. for the purposes of thermal analysis, the chip is treated as a thermal unit, with the highest junction tempera- ture reflected in the ja from table 14. the value of ja is based on measurements taken with the parts mounted on a jedec standard, 4-layer board with fine width traces and still air. under normal operating conditions, the adum6210 / adum6211/ adum6212 can operate at full load across the full temperature range without derating the output current. propagation delay parameters propagation delay is a parameter that describes the time it takes a logic signal to propagate through a component (see figure 27). the propagation delay to a logic low output may differ from the propagation delay to a logic high. input (v ix ) output (v ox ) t plh t phl 50% 50% 11042-025 figure 27. propagation delay parameters pulse width distortion is the maximum difference between these two propagation delay values and is an indication of how accurately the input signal timing is preserved. channel-to-channel matching refers to the maximum amount the propagation delay differs between channels within a single adum6210/ adum6211/ adum6212 component. propagation delay skew refers to the maximum amount the propagation delay differs between multiple adum6210 / adum6211/ adum6212 devices operating under the same conditions. emi considerations the dc-to-dc converter section of the adum6210 / adum6211/ adum6212 components must, of necessity, operate at a very high frequency to allow efficient power transfer through the small transformers. this creates high frequency currents that can propagate in circuit board ground and power planes, causing edge and dipole radiation. grounded enclosures are recom- mended for applications that use these devices. if grounded enclosures are not possible, follow good rf design practices in the layout of the pcb. see the an-0971 application note for the most current pcb layout recommendations for the adum6210/ adum6211/ adum6212 . dc correctness and magnetic field immunity positive and negative logic transitions at the isolator input cause narrow (~1 ns) pulses to be sent to the decoder via the transformer. the decoder is bistable and is, therefore, either set or reset by the pulses, indicating input logic transitions. in the absence of logic transitions at the input for more than 1.6 s, periodic sets of refresh pulses that are indicative of the correct input state are sent to ensure dc correctness at the output. if the decoder receives no internal pulses of more than approximately 6.4 s, the input side is assumed to be unpowered or nonfunctional, in which case, the isolator output is forced to a default low state by the watchdog timer circuit. this situation should occur in the adum6210/ adum6211/ adum6212 only during power-up and power-down operations. the limitation on the adum6210 / adum6211 / adum6212 magnetic field immunity is set by the condition in which induced voltage in the transformer receiving coil is sufficiently large to either falsely set or reset the decoder. the following analysis defines the conditions under which this can occur. the 3.3 v operating condition of the adum6210/ adum6211/ adum6212 is examined because it represents the most susceptible mode of operation. the pulses at the transformer output have an amplitude of >1.5 v. the decoder has a sensing threshold of about 0.5 v, thus estab- lishing a 0.5 v margin in which induced voltages can be tolerated. the voltage induced across the receiving coil is given by v = ( ?d /dt )? r n 2 ; n = 1, 2, , n where: is the magnetic flux density (gauss). r n is the radius of the n th turn in the receiving coil (cm). n is the number of turns in the receiving coil. given the geometry of the receiving coil in the adum6210/ adum6211/ adum6212 and an imposed requirement that the induced voltage be, at most, 50% of the 0.5 v margin at the decoder, a maximum allowable magnetic field is calculated as shown in figure 28. magnetic field frequency (hz) 100 maximum allowable magnetic flux density (kgauss) 0.001 1m 10 0.01 1k 10k 10m 0.1 1 100m 100k 11042-026 figure 28. maximum allowable external magnetic flux density
data sheet adum6210/adum6211/adum6212 rev. 0 | page 21 of 24 for example, at a magnetic field frequency of 1 mhz, the maximum allowable magnetic field of 0.2 kgauss induces a volta ge of 0.25 v at the receiving coil. this is about 50% of the sensing threshold and does not cause a faulty output transition. similarly, if such an event occurs during a transmitted pulse (and is of the worst - case polarity), it reduces the received pulse f rom >1.0 v to 0.75 v, which is still well above the 0.5 v sensing threshold of the decoder. the preceding magnetic flux density values correspond to specific current magnitudes at given distances from the adum6210 / adum6211 / adum6212 transformers. figure 29 expresses these allowable current magnitudes as a function of frequency for selected distances. as shown in figure 29 , the adum6210 / adum6211 / adum6212 are extremely immune and can be affected only by extremely large currents operated a t high fre - quency very close to the component. for the 1 mhz example, a 0.5 ka current , placed 5 mm away from the adum6210 / adum6211 / adum6212 , is required to affec t component operation. m a g n e t i c f i e l d f r e q u e nc y ( h z) m a x i m u m a ll o w ab l e curr e n t ( k a ) 1 k 10 0 1 0 1 0 . 1 0 . 0 1 1 k 10 k 100 m 100 k 1 m 10 m d i s t anc e = 5m m d i s t anc e = 1 m d i s t anc e = 100m m 1 1042-027 figure 29 . maximum allowable current for various current - to- adum621 x spacings note that , in combinations of strong magnetic field and high frequency, any loops formed by pcb traces c an induce error voltages that are sufficiently large to trigger the thresholds of succeeding circuitry. exercise care in the layout of such traces to avoid this possibility. power consumption the v ddp power supply input provides power only to the converter. power for the data c hannels is provided through v dd1 and v dd2 . these power supplies can be connected to v ddp and v iso , if desired ; or the supplies can receive power from an independent source. the converter should be treated as a standalone supply to be utilized at the di scretion of the designer. the v dd1 or v dd2 supply current at a given channel of the adum6210 / adum6211 / adum6212 isolator is a function of the supply voltage, the dat a rate of the channel, and the output load of the channel. for each input channel, the supply current is given by i ddi = i ddi ( q ) f 0.5 f r i ddi = i ddi( d) (2 f ? f r ) + i ddi ( q ) f > 0.5 f r for each output channel, the supply current is given by i ddo = i ddo ( q ) f 0.5 f r i ddo = ( i ddo( d ) + (0.5 10 ? 3 ) c l v ddo ) (2 f ? f r ) + i ddo( q ) f > 0.5 f r where: i ddi (d) , i ddo (d) are the input and output dynamic supply currents per channel (ma/mbps). i ddi (q) , i ddo(q) are the specified input and output quiescent suppl y currents (ma). f is the input logic signa l frequency (mhz); it is half the input data rate, expressed in units of mbps. f r is the input stage refresh rate (mbps). c l is the output load capacitance (pf). v ddo is the output supply voltage (v). to calculat e the total v dd1 and v dd2 supply current, the supply currents for each input and output channel corresponding to v dd1 and v dd2 are calculated and totaled. figure 18 and figu re 19 show per - channel supply currents as a function of data rate for an unloaded output condition. figure 20 shows the per - channel supply current as a function of data rate for a 15 pf output condition. figure 21 through figure 23 show the total v dd1 and v dd2 supply current as a function of data rate for adum6210 / adum6211 / adum6212 channel configurations.
