MP8774H

MP8774H

12A, Wide-Input 3V to 18V, 1.4MHz Synchronous Step-Down Converter with PG and External Soft Start in 3mmx3mm QFN Package

Datasheet

Description

The MP8774H is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The MP8774H offers a very compact solution that achieves 12A of continuous output current with excellent load and line regulation over a wide input range. The MP8774H uses synchronous mode operation for higher efficiency over the output current load range.

Constant-on-time (COT) control operation provides very fast transient response, easy loop design, and very tight output regulation.

Full protection features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown.

The MP8774H requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-16 (3mmx3mm) package.
