MPM3840GQV - Synchronous Step-Down Converter

Download the MPM3840GQV datasheet PDF. This datasheet also covers the MPM3840 variant, as both devices belong to the same synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MPM3840 is a DC/DC module that includes a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs and an inductor.

The MPM3840 can provide 4A of continuous output current from a 2.8V to 5.5V input voltage with excellent load and line regulation.

Key Features

  • include cycle-by-cycle current limiting and thermal shutdown. The MPM3840 requires a minimal number of readily available, standard, external components and is available in an ultra-small QFN-20 (3mmx5mmx1.6mm) package.

The Future of Analog IC Technology MPM3840 2.8V-5.5V, 4A, Power Module, Synchronous Step-Down Converter with Integrated Inductor DESCRIPTION The MPM3840 is a DC/DC module that includes a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs and an inductor. The MPM3840 can provide 4A of continuous output current from a 2.8V to 5.5V input voltage with excellent load and line regulation. The MPM3840 is ideal for powering portable equipment that run on a single-cell Lithium-ion (Li+) battery. The output voltage can be regulated as low as 0.6V. Only input capacitors, output capacitors, and feedback (FB) resistors are required to complete the design.
