PM8903ATR
LTB3 A STEP-DOWN MONOLITHIC SWITCHING REGULATOR
Description
General part information
PM8903A Series
The PM8903A is a high efficiency monolithic step-down switching regulator designed to deliver up to 3 A continuous current. The IC operates from 2.8 V to 6 V input voltage (VIN).
The PM8903A features low-resistance integrated nMOS and proprietary pulse-skipping mode for optimum efficiency over all the loading range.
The voltage mode control loop allows the widest range of output filters. Current sense is internally thermally compensated for optimum precision.
