MP8758H

10A, 22V, Synchronous Step-Down Converter with Hiccup OCP, PFM/PWM Mode Selection

Datasheet

Description

The MP8758H is a fully integrated, high-frequency, synchronous, rectified, step-down converter. It offers a very compact solution to achieve a 10A output current with excellent load and line regulation over a wide input supply range. The MP8758H employs a constant-on-time (COT) control scheme, which provides fast transient response and eases loop stabilization. The COT control scheme provides a seamless transition into PFM mode at light-load operation, which boosts light-load efficiency. An open-drain power good signal indicates that the output voltage is within its nominal voltage range. Full protection features include over-current protection (OCP), over-voltage and under-voltage protection (OVP, UVP), and thermal shutdown. The MP8758H requires a minimal number of readily available, external components and is available in a QFN-21 (3mmx4mm) package.
