Datasheet

概要

The MP2331H is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The MP2331H offers a very compact solution that achieves 2A of continuous output current with excellent load and line regulation over a wide input range. The MP2331H 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 MP2331H requires a minimal number of readily available, standard, external components and is available in a space-saving SOT583 package.
