MP38892DN-LF Power Management IC Buck Switching Regulator IC Positive Adjustable 0.8V 1 Output 6A

6A, 42V, 420KHz Step-Down Converter with Synchronizable Gate Driver

DESCRIPTION

The MP38892 is a monolithic step-down switch mode converter with a built in, internal high-side power MOSFET. It achieves 6A continuous output current 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 MP38892 requires a minimum number of readily available standard external components and is available in an 8-pin SOIC package with exposed pad.
