The TPS54335-1ADRCT is a 4.5V to 28V input, 3A output, synchronous step down DC/DC converter in 10 pin VSON package. This device includes an integrated low side switching FET that eliminates the need for an external diode which reduces component count. Efficiency is maximized through the integrated 128mohm and 84mohm MOSFETs, low IQ and pulse skipping at light loads. Using the enable pin, the shutdown supply current is reduced to 2µA. This step-down (buck) converter provides accurate regulation for a variety of loads with a well regulated voltage reference that is 1.5% over temperature. Cycle-by-cycle current limiting on the high side MOSFET protects IC in overload situations and is enhanced by a low side sourcing current limit which prevents current runaway. It is used in consumer applications such as a digital TV (DTV), set top box, LCD display, CPE (cable modem, Wi-Fi router), DLP projectors, smart meters, battery chargers, 5V, 12V and 24V distributed power bus supply.
