MP2359

1.2A, 24V, 1.4MHz

Step-Down Converter in a TSOT23-6

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP2359 is a monolithic step-down switch

mode converter 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.
