MPQ2128DG - Step-Down Converter

Download the MPQ2128DG datasheet PDF. This datasheet also covers the MPQ2128 variant, as both devices belong to the same step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MPQ2128 is a 3MHz, constant-frequency, current-mode, PWM, step-down converter.

It has an integrated main switch and synchronous rectifier that make it ideal for low-voltage conversions.

The MPQ2128 can supply up to 1A load current from a 2.5V-to-6V input voltage.

`DESCRIPTION The MPQ2128 is a 3MHz, constant-frequency, current-mode, PWM, step-down converter. It has an integrated main switch and synchronous rectifier that make it ideal for low-voltage conversions. The MPQ2128 can supply up to 1A load current from a 2.5V-to-6V input voltage. The output voltage can go as low as 0.6V. Additional features include <1μA shutdown current, internal soft-start, cycle-by-cycle overcurrent protection, short-circuit protection, and thermal shutdown. The MPQ2128 is available in a 2mm×2mm 8pin QFN package. MPQ2128 2.5V-to-6V Input, 3MHz, 1A Synchronous, Step-Down Converter Available in AEC-Q100 FEATURES • Meets Automotive Requirements • Highly Efficient: Up to 95% • 3MHz Constant-Switching Frequency • 1A Available Load Current • 2.
