Product Description

The MP2229 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a  compact solution to achieve a 6A continuous output current over a wide input-supply range with excellent load and line regulation. The MP2229 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 include over-current protection (OCP) and thermal shutdown (TSD).

The MP2229 requires a minimal number of readily available, standard, external components and is available in a space-saving 3mm x 3mm 14-pin QFN package.
