Product Descriptions

The MP8642 is a dual monolithic step-down switch mode converter with built-in internal power MOSFETs. It achieves 3A continuous output current for each output over a wide input supply range with excellent load and line regulation.

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

Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown.

The MP8642 requires a minimum number of readily available standard external components.
