MP1477

The MP1477 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The MP1477 offers a very compact solution that achieves 3A of continuous output current, with excellent load and line regulation over a wide input range. The MP1477 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 MP1477 requires a minimal number of readily available, standard external components, and is available in a space-saving SOT563 (1.6mmх1.6mm) package.
