- 7 - ts30011/12/13 version 1. 6 specifications subject to change www.triunesystems.com copyright ? 2012 , triune systems, llc functional description t he ts30011/ 12 /13 current - mode synchronous step - down power supply product is ideal for use in the commercial, industrial, and automotive market segments. it includes flexibility to be used for a wide range of output voltages and is optimized for high efficiency power conversion with low r dson integrated synchronous switch es. a 1mhz i nternal switching frequency facilitates low cost lc filter combination s . additionally, the fixed output version s enable a minimum external component count to provide a complete regulation solution with only 4 external components: an input bypass capacitor , an inductor, an output capacitor, and the bootstrap capacitor. the regulator automatically transitions between pfm and pwm mode to maximize efficiency for the load demand. the ts30011/12 /13 was designed to provide these system benefits: ? reduced board real estate ? lower system cost o lower cost inductor o low external parts count ? ease of design o bill of materials and suggested board layout provided o power good output o integrated compensation network o wide input voltage range ? robust solution o over current, over vo ltage and over temperature protection detailed pin description unregulated input, vcc this terminal is the unregulated input voltage source for the ic. it is recommended that a 10uf bypass capacitor be placed close to the device for best performance . since this is the main supply for the ic, good layout practices need to be followed for this connection. bootstrap control , bst this t erminal will provide the bootstrap voltage required for the up per internal nmos switch of the buck regulator. an extern al ceramic capacitor placed between the bst i nput terminal and the vsw pin will provide the necessary voltage for the upper switch. in normal operation the capacitor is re - charged on every low side synchronous switching action. in the case of where the swi tch mode approaches 100% duty cycle for the high side fet, the device will automatically reduce the duty cycle switch to a minimum off time on every 8 th cycle to allow this capacitor to re - charge. sense feedback, fb t his is the input termina l for the output voltage feedback. for the fixed mode version s , this should be hooked directly to v out . the connection on the pcb should be kept as short as possible, and should be made as close as possib le to the capacitor. the trace should not be shar ed with any other connection. (figure 23) for adjustable mode versions, this should be connected to the external resistor divid er. to choose the resistors, use the following equation: v out = 0.9 (1 + r top /r bot ) the input to the fb pin is high impedance, and input current should be less than 100na. as a result, good layout practices are required for the feedback resistors and feedback traces. when using the adjustable version, the feedback trace should be kept as short as possible and minimum w idth to reduce stray capacitance and to reduce the injection of noise. for the adjustable version, the ratio of vcc/vout cannot exceed 16.
- 8 - ts30011/12/13 version 1. 6 specifications subject to change www.triunesystems.com copyright ? 2012 , triune systems, llc switching output, vsw this is the switching node of the regulator. it should be connected directly to the 4.7uh inductor with a wide, short trace and to one end of the bootstrap capacit or. it is switching between vcc and pgnd at the switching frequency. g round, gnd this ground is used for the majority of the device including the analog reference , control loop, and other circuits . power ground, p gnd this is a separate ground connection used for the low side sync hron ous switch to isolate switching noise from the rest of the device . (figure 23) enable, high - voltage, en this is the input terminal to activate the regulator. t he input threshold is ttl/cmos compatibl e . it also has an internal pull - up to ensure a stable state if the pin is disconnected. p ower g ood output, pg this is an open drain , active low output. th e switched mode output voltage is monitored and t he pg line will remain low until the output voltage reaches the v out - uv threshold. once the in ternal comparator detects the output voltage is above the desired threshol d , an internal delay timer is activated and the pg line is de - asserted to high once this delay timer expires. in the event the output voltage decreases below v out - uv , the pg line will be asserted low and remain low until the output rises abov e v out - uv and the delay timer times out. see figure 2 for the circuit schematic for the pg signal. internal protection details internal current limit the current through the high side fet is sensed on a cycle by cycle basis and if current l imit is reached, it will abbreviate the cycle. in addition, the device senses the fb pin to identify hard short conditions and will direct the vsw output to skip 4 cycles if current limit occurs when fb is low . this allow s current built up in the inductor during the minimum on time to decay sufficiently . current limit is always active when the regulator is enabled. soft start ensures current limit does not prevent regulator startup. u nder extended over current conditions (such as a short) , the device will automatically d isable . once the over current condition is removed, the device returns to normal operation automatically. (alternately the factory can configure the devic es nvm to shutdown the regulator if an extended over current event is detected and require a toggle of the enable pin to return the device to normal operation.) thermal shutdown if the temperature of the die exceeds 170 c (typical), the vsw outputs will tri - state to protect the device from damage. the pg and all other protection circuitry will stay active to inform t he system of the failure mode. once the device cools to 160 c (typical), the device will start up again, following the normal soft start sequence . if the device reaches 170 c, the shutdown/res tart sequence will repeat. reference soft start the reference in this device is ramped at a rate of 4m s to prevent the output from overshoot during startup. this ramp restarts whenever there is a rising edge sensed on the enable pin. thi s occurs in both the fixed and adjustable versions. during the soft start ramp, current limit is still active, and will still protect the device in case of a short on the output. output overvoltage if the output of the regulator exceeds 10 3 % of the regulation voltage, the vsw outputs will tri - state to protect the device from damage. this check occurs at the start of each switching cycle . i f it occurs during the middle of a cycle, the switching for that cycle will complete, and the vsw out puts will tri - state at the beginning of the next cycle. vcc under - voltage lockout t he device is held in the off state until vcc reaches 4 . 5v (typical). there is a 500mv hysteresis on this input , which requires the input to fall below 4 . 0 v (typical) before the device will disable.

(figure 23) the main guidelines are the following: ? provide low inductive and resistive paths for loops with high di /dt, ? provide low capacitive paths with respect to all the other nodes for traces with high di/dt, ? sensitive nodes not assigned to power transmission should be referenced to the analog signal ground (gnd) and be always separated from the power ground (pgnd) . the negative ends of c bypass , c out and the schottky diode d catch (optional) should be placed close to each other and connected using a wide trace. vias must be used to connect the pgnd node to the ground plane. the pgnd node must be placed as close as possible to the ts30011/12 /13 pgnd pins to avoid additional voltage drop in traces. the bypass capacitor c bypass (optionally paralleled to a 0.1f capacit or) must be placed close to the vcc pins of ts30011/12 /13 . the inductor must be placed close to the vsw pins and connected directly to c out in order to minimize the area between the vsw pin, the inductor, the c out capacitor and the pgnd pins. the trace ar ea and length of the switching nodes vsw and bst should be minimized. for the adjustable output voltage version of the ts30011/12 /13 , feedback resistors r bot and r top are required for vout settings greater than 0.9v and should be placed close to the ts30 011/12 /13 in order to keep the traces of the sensitive node fb as short as possible and away from switching signals. r bot should be connected to the analog ground pin (gnd) directly and should never be connected to the ground plane. the analog ground trace (gnd) should be connected in only one point to the power ground (pgnd). a good connection point is under the ts30011/12 /13 package to the exposed thermal pad and vias which are connected to pgnd. r top will be connected to the v out node using a trace that ends close to the actual load. for fixed output voltage versions of the ts30011/12 /13 , r bot and r top are not required and the fb pin should be connected directly to the vout. t s 3 0 0 1 1 / 1 2 / 1 3 v o u t 2 . 5 v p g n d v s w v c c f b g n d b s t v c c p g p g r t o p 1 7 . 8 k r b o t 1 0 k r p u p 1 0 k ( o p t i o n a l ) v o u t e n e n c b y p a s s 1 0 u f 3 5 v c b s t 2 2 n f l o u t 4 . 7 u h c o u t 1 2 2 u f 1 0 v c o u t 2 2 2 u f 1 0 v c b y p a s s 2 0 . 1 u f ( o p t i o n a l ) d c a t c h ( o p t i o n a l )
