LTC3565 Datasheet Synchronous Step-down DC/dc Converter

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC3565 1.25A, 4MHz, Synchronous Step-Down DC/DC Converter.

General Description

The LTC®3565 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 1mm or less in height.

The output voltage is adjustable from 0.6V to 5.5V.
