MP9148GJ Datasheet Sync Buck Regulator

Manufacturer: Monolithic Power Systems

Overview: The Future of Analog IC Technology MP9148 6V, 1A, Low Quiescent Current Dual, SYNC Buck.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MP9148 is an internally-compensated, 1MHz fixed-frequency, dual PWM, synchronous, step-down regulator.

The MP9148 operates from a 2.7V-to-6V input, generates an output voltage as low as 0.608V, and has a 45µA quiescent current that makes it ideal for powering portable equipment that runs on a single cell lithium-ion (Li+) battery.

The MP9148 integrates dual 100mΩ high-side switches and 40mΩ synchronous rectifiers for high efficiency without an external Schottky diode.
