LTC3417A Datasheet Dual Synchronous 1.5a/1a 4mhz Step-down DC/dc Regulator

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC3417A.

General Description

The LTC®3417A is a dual constant frequency, synchronous step-down DC/DC converter.

Intended for medium power applications, it operates from a 2.25V to 5.5V input voltage range and has a constant programmable switching frequency, allowing the use of tiny, low cost capacitors and inductors 2mm or less in height.

Each output voltage is adjustable from 0.8V to 5V.
