IC revision1.0

Description

The MP2371 is a monolithic step-down switch mode converter with a built-in internal power MOSFET. It achieves 1.8A 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 MP2371 requires a minimum number of readily available standard external components. The MP2371 is available in a 2mm x 2mm QFN8 package.
