LT8609S Datasheet

LT8609S 2A/3A Peak Synchronous Step-Down Regulator

The LT®8609S is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 1.7µA of non-switching quiescent current. The LT8609S can deliver 2A of continuous current with peak loads of 3A (<1sec) to support applications such as GSM transceivers whi.
