MP28257DD Datasheet Synchronous Step-down Converter

Manufacturer: Monolithic Power Systems

Overview: MP28257 4A, Fast Transient, 4.2V-to-20V Input Synchronous Step-Down Converter The Future of Analog IC.

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

General Description

The MP28257 is a fully-integrated, synchronous, O step-down, switch-mode converter with a programmable frequency.

It offers a very F compact solution that can provide up to 4A of continuous output current over a wide input supply range with excellent load and line D regulation, and can operate at high efficiency over a wide output current load range.

E Constant-on-time control mode provides fast transient response and eases loop stabilization.
