LT8610AB - 3.5A Synchronous Step-Down Regulator

Download the LT8610AB datasheet PDF. This datasheet also covers the LT8610A variant, as both devices belong to the same 3.5a synchronous step-down regulator family and are provided as variant models within a single manufacturer datasheet.

General 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.
