A Family of fully integrated, synchronous Step-Down Converters

The MP147x is a fully integrated, high-frequency, synchronous rectified, step-down, switch-mode converter with internal power MOSFETs by MPS. The MP147x offers a very compact solution that achieves 2A (MP1476/L) or 3A (MP1477/H) of continuous output current with excellent load and line regulation over a wide input range.


Full protection features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown.

The MP147x-Series requires a minimal number of readily available, standard, external components and is available in a space-saving SOT563 package.
