LT8610A - 3.5A Synchronous Step-Down Regulator

Description

The LT®8610A/LT8610AB series are compact, high efficiency, high speed synchronous monolithic step-down switching regulators that consume only 2.5µA of quiescent current.

Compared to the LT8610, they have higher maximum output currents of 3.5A and a faster minimum switch-on time of 30ns.
