LTC3636
LTC3636-1

Demonstration circuit DC2335A is a dual output regulator consisting of two constant-frequency step-down converters, based on the LTC3636 monolithic dual channel synchronous buck regulator. The DC2335A has an input voltage range of 3.1V to 20V, with each regulator capable of delivering up to 6A of output current. The DC2335A can operate in either Burst Mode^® operation or forced continuous mode. In shutdown, the DC2335A can run off of 13µA typical total input current at 12V input. The DC2335A is a very efficient circuit: up to 92% for 3.3V output at 6A load, 5V input. The DC2335A uses the 28-Pin QFN package LTC3636EUFD, which has exposed pads on the bottom side of the IC for better thermal performance. These features, plus a programmable operating frequency range from 500kHz to 4MHz (2MHz switching frequency with the RT pin connected to INTV_CC), make the DC2335A demo board an ideal circuit for use in industrial or distributed power applications.
