LM43603 Overview
The LM43603 regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 3 A of load current from an input voltage ranging from 3.5 V to 36 V (42 V abs max). The LM43603 provides exceptional efficiency, output accuracy and dropout voltage in a very small solution size. An extended family is available in 0.5-A, 1-A, and 2-A load current options in pin to pin patible packages.
