MP9943

The EV9943-Q-00A demonstrates MPS’s MP9943, a high-frequency, synchronous, rectified, step-down converter with built-in high-side and low-side power MOSFETs. The MP9943 offers a very compact solution to achieve a 3A peak output current with excellent load and line regulation over a wide input supply range. The MP9943 has synchronous mode operation for higher efficiency over the output current load range.

Current-mode operation provides fast transient response and eases loop stabilization.

Full protection features includes over-current protection and thermal shutdown.

The MP9943 requires a minimal number of readily-available s is available in a space-saving QFN8 (3mm x 3mm) package.
