The LTC3407-4 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. Internal synchronous 0.35, 1.2A power switches provide high efficiency without the need for external Schottky diodes.
