Description

The MIC2159 is a high efficiency, simple to use synchronous buck controller ICs housed in a 10-pin MSOP ePAD package. The MIC2159 switches at 400kHz, allowing the smallest possible external components and is designed to drive loads up to 30A. The devices feature high output driver capability, combined with an all n-channel synchronous architecture.

The MIC2159 operates from a 3V to 14.5V input and can be configured to generate output voltages as low as 0.8V. Efficiencies of over 95% can be achieved within the smallest possible printed circuit board space area.

The MIC2159 is available in a thermally capable 10-pin ePAD MSOP package, with an junction operating range from 40°C to +125°C.
