MP1477H - Step-Down Converter

Description

The MP1477H is a fully integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs.

The MP1477H offers a very compact solution that achieves 3A of continuous output current with excellent load and line regulation over a wide input range.

Features

  • include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown. The MP1477H requires a minimal number of readily available, standard, external components and is available in a space-saving SOT563 (1.6mmх1.6mm) package.

MP1477H 17V, 3A, 1.2MHz, High-Efficiency, Synchronous, Step-Down Converter in a SOT563 Package DESCRIPTION The MP1477H is a fully integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The MP1477H offers a very compact solution that achieves 3A of continuous output current with excellent load and line regulation over a wide input range. The MP1477H 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.
