Datasheet Summary
17V, 4A, 600kHz, High-Efficiency, Synchronous, Step-Down Converter in an SOT563 Package
DESCRIPTION
The MP9459 is a fully integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The device is a pact solution that achieves 4A of output current over a wide input range with excellent load and line regulation. It 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),...
