MP1657 Description
The MP1657 is a fully integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The MP1657 offers a very pact solution that achieves 2A of continuous output current with excellent load and line regulation over a wide input range. The MP1657 uses synchronous-mode operation for higher efficiency over the output current-load range.
