General Description

The LTC®3407-4 is a dual, constant frequency, synchronous step down DC/DC converter.

Intended for low power applications, it operates from 2.5V to 5.5V input voltage range and has a constant 2.25MHz switching frequency, allowing the use of tiny, low cost capacitors and inductors with a proﬁle ≤1mm.

Each output voltage is adjustable from 0.6V to 5V.
