Description	Triple Buck Regulator
Datasheet	LTC3569 Datasheet

The LTC®3569 contains three monolithic, synchronous step-down DC/DC converters.

Intended for medium power applications, it operates over a 2.5V to 5.5V input voltage range.

The operating frequency is adjustable from 1MHz to 3MHz, allowing the use of tiny, low cost capacitors and inductors.
