Monolithic Power Systems MP2370

Description

The MP2370 is a monolithic step-down white LED driver with a built-in power MOSFET. It achieves 1.2A peak 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 MP2370 requires a minimum number of readily available standard external components. The MP2370 is available in a TSOT23-6 package
