dual channel PWM step-down DC/DC converter

working under an input voltage range of 2.5V to

5.5V. It integrates two PWM synchronous

step-down DC-DC converters. 100% duty cycle

capability extends battery life in portable devices,

while the quiescent current (one channel) is

200μA with no load, and drops to <1μA in

shutdown.

Each DC-DC converter has independent enable

input

and

short-circuit

protection

allowing

versatile power sequence combination.
