LTC3568 Datasheet Synchronous Step-down DC/dc Converter

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®3568 is a constant frequency, synchronous step- down DC/DC converter.

Intended for medium power applications, it operates from a 2.5V to 5.5V input voltage range and has a user configurable operating frequency up to 4MHz, allowing the use of tiny, low cost capacitors and inductors 2mm or less in height.

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