75w, dual output, mixed-voltage dc/dc converters xcp series 5v & 3.3v outputs/returns the bcp series outputs (pins 7 & 10) and returns (pins 6 & 9) are isolated from the +v in and ? in inputs (pins 4 & 1) via a transformer and opto-coupled transistors. the +5v return (pin 6) and +3.3v return (pin 9) are connected internal to the dc/dc converter. though the returns are common within the dc/dc converter, the regulating control loop for each output is sensed directly at its respective output and return pins. in order to maintain optimum regulation if ground plane is not used, it is critical that pc board layouts also return each output to its corresponding return pin. filtering and noise reduction all bcp dc/dc converters achieve their rated ripple and noise speci cations using the external input and output capacitors speci ed in the performance/ functional speci cations table. in critical applications, input/output noise may be further reduced by installing additional external i/o caps. input capacitors should be selected for bulk capacitance, low esr and high rms-ripple-current ratings. output capacitors should be selected for low esr and appropriate frequency response. all caps should have appropriate voltage ratings and be mounted as close to the converters as possible. the most effective combination of external i/o capacitors will be a function of your particular load and layout conditions. our applications engineers will be pleased to recommend potential solutions and can discuss the possibility of our modifying a devices internal ltering to meet your speci c requirements. contact our applications engineering group for additional details. input fusing certain applications and/or safety agencies may require the installation of fuses at the inputs of power conversion components. fuses should also be used if the possibility of sustained, non-current-limited, input-voltage polarity reversals exists. for datel bcp dc/dc converters, you should use slow- blow type fuses with values no greater than the following. v in range fuse value "d24" models 6 amps "d48" models 4 amps fuses should be installed in the +input line. input overvoltage/undervoltage shutdown and start-up threshold under normal start-up conditions, devices will not begin to regulate until the ramping-up input voltage exceeds the start-up threshold voltage (35v for "d48" models). once operating, devices will not turn off until the input voltage drops below the undervoltage shutdown limit (32v for "d48" models). subsequent re-start will not occur until the input is brought back up to the start-up threshold. this built-in hysteresis prevents any unstable on/off situations from occurring at a single voltage. input voltages exceeding the input overvoltage shutdown speci cation listed in the performance/functional speci cations will cause the device to shut- down. a built-in hysteresis (2v typical for "d24" models, 4v typical for "d48" models) will not allow the converter to restart until the input voltage is suf ciently reduced. start-up time the v in to v out start-up time is the interval between the time at which a ramping input voltage crosses the turn-on threshold point and the fully- loaded output voltage enters and remains within its speci ed accuracy band. actual measured times will vary with input source impedance, external input capacitance, and the slew rate and nal value of the input voltage as it appears to the converter. the on/off to v out start-up time assumes the converter has its nominal input voltage applied but is turned off via the on/off control. the speci cation de nes the interval between the time at which the converter is turned on and the fully loaded output voltage enters and remains within its speci ed accuracy band. on/off control (standard feature) the on/off control (pin 3) may be used for remote on/off operation. as shown in figure 1a, the control pin is referenced to the ?nput (pin 1) and will be pulled to a high state internally. the standard bcp converter (no suf x) is designed so that it is enabled when the control pin is left open and disabled when the control pin is pulled low (to less than +0.6v relative to ?nput). dynamic control of the on/off function is best accomplished with a mechanical relay or an open-collector/open-drain drive circuit (optically isolated if appropriate). the drive circuit should be able to sink approximately 1ma for logic low. the on/off control function is designed such that the converter can be dis- abled (pin 3 pulled low for no-suf x models) while input power is ramping up and then "released" once the input has stabilized. for bcp converters con gured with the negative-polarity option on the on/off control pin ("n" suf x added to part number), operation is opposite to that described above. the converter is disabled when the on/off control pin is left open and enabled when pulled low. technical notes sync function (optional feature) in critical applications employing multiple switching dc/dc converters, it may be necessary to intentionally synchronize the switching of selected converters. the bcp series offers an optional sync function ("s" suf x) in place of the on/off control on pin 3. the sync pin will self-con gure as either a slave or master, depending on the circuit application. figure 1a. no suf x figure 1b.

bcp models 75w, dual output, mixed-voltage dc/dc converters if the sync pin detects the appropriate input signal, it will con gure itself as a slave; if no signal is detected, it will generate master sync pulses. synchronization of converters requires that the master switching frequency exceed the slave frequency by a minimum of 60khz. at the start of each dc/dc converter switching cycle, an internally generated 200-450ns pulse will be present at the sync pin. if, however, the unit receives an external sync pulse, the dc/dc converters switching cycle will be terminated and a new cycle initiated. since the master frequency is higher than the slave switching frequency, the slave cycles are always terminated prematurely, thereby never allowing internal synch pulses to be generated. the external signals rising edge initiates the slave sync process. external signals must adhere to min./ max. limits stated in performance/functional speci cations. operating the bcp series dc/dc converters at higher switching frequencies via the external sync function will result in a slight degradation of ef ciency. contact datel for further information. output overvoltage protection each voltage output of the bcp series converter is independently monitored via an auxiliary winding in the output inductor. if the output voltage should rise to a level which could be damaging to the load circuitry (see performance/functional speci cations for limits), the overvoltage circuitry will power down the pwm controller and latch off the dc/dc converter. the device must now be restarted by powering cycling v in . current limiting when output current demands exceed the maximum output current rating by 107% to 133%, the dc/dc converter will go into a current limiting mode. in this condition the output voltage decreases proportionately as the output current increases, thereby maintaining a somewhat constant power dissipa- tion?eferred to as power limiting (see figure 2). as the load approaches a short circuit, the output current will continue to increase until it reaches the rated short circuit current limit. bcp-5/15-3.3/15-d24, d48 current limiting characteristics (nominal v in ) output voltage v out (volts) output current, i out (amps) 6.00 5.00 4.00 3.00 2.00 1.00 0 5v output 3.3v output 15.2 15.7 16.2 16.7 17.2 17.8 18.3 18.8 19.3 19.8 20.3 20.9 21.9 22.4 22.6 23.5 24 25 26 short circuit condition as described under "current limiting," when the bcp series dc/dc con- verter output is subjected to a short circuit condition, the output current will remain at the short circuit current limit . in this state there is negligible power dissipated in the load. therefore, most of the input power is dissipated within the converter, causing the internal temperature to increase. if this condition persists, thermal shutdown will activate and shutdown the dc/dc converter. when the internal temperature is suf ciently decreased, the converter will self-start. thermal shutdown the bcp series is equipped with thermal shutdown circuitry. if the internal temperature of the dc/dc converter rises above the designed operating temperature, a precision temperature sensor will power down the unit. when the internal temperature decreases below the threshold of the temperature sensor the unit will self-start. input reverse-polarity protection upon applying a reverse-polarity voltage to the dc/dc converter, an internal diode will be forward biased and draw excessive current from the power source. therefore, it is required that the input current be limited be either an appropriately rated input fuse or a current limited power source. figure 2. current limiting characteristics heat sinks for bcp series datel offers two standard heat sinks that can be mounted to the half-brick package to extend the converter's operating temperature range. along with the standard 2.3" x 2.4" x 0.5" (hs-cp) heat sink, datel has designed a low-pro le heat sink for height-restricted applications. this new heat sink (hs-cplp2) is designed with radiant ns that extend 0.51" beyond either side of the 2.4" dimension of the bcp package. the convenience of this design is that the nned extensions protrude only 0.31" below the top surface of the dc/dc converter, allowing components with a pro le height less than 0.215" to be mounted on the pc board below the heat sink. therefore, while the surface area of the low-pro le heat sink measures 2.3" x 3.5", pcb real estate is unaffected. for optimum thermal performance in a natural convection application, the low-pro le heat sink should be mounted with the ns vertically oriented. both models are shipped with 0.009" sellf-adhesive thermal pad and mounting screws. 6 5 4 3 2 1 0 0 100 200 300 400 500 600 70 0 air velocity (ft./min.) hs-cp thermal resistance ? c watt hs-cplp2 hs-cp and hs-cplp2 heat sink performance vs. air flow (@ 10.5 watts power dissipation) 5
