Description
The LTC3548M is a dual, constant frequency, synchronous step down DC/DC converter designed for low power applications. It has an input voltage range of 2.5V to 5.5V and a constant switching frequency of 2.25MHz. This allows for the use of small, low-cost capacitors and inductors with a profile of ≤1.2mm. Each output voltage on the LTC3548M is adjustable from 0.6V to 5V. It features internal synchronous 0.35Ω, 0.7A/1.2A power switches, eliminating the need for external Schottky diodes.
