MP2370

1.2A, 24V, 1.4MHz Buck WLED Driver

Datasheet

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 cyclebycycle 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.
