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