MPM3805

6V Input, 0.6A Module Synchronous Step-down Converter with Integrated Inductor

Datasheet

概要

The MPM3805 is a module with monolithic step-down switch mode converter with built-in internal power MOSFETs and inductor. It's designed to simplify power system design and provide ease of use. The DC-DC module has a small surface-mount 3mm x 2.5mm x 0.9mm QFN package. It achieves 0.6A continuous output current from a 2.5V to 6V input voltage with excellent load and line regulation. The output voltage can be regulated as low as 0.6V. For adjustable output, only input, output capacitors and FB resistors are needed to complete the design. The Constant-On-time control scheme provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The MPM3805 is ideal for a wide range of applications including high performance DSPs, FPGAs, PDAs, portable instruments and storage.
