LTC3569 Datasheet (Linear Technology)

LTC3569, Triple Buck Regulator

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.

The three
