DESCRIPTION

The MP2160 is a monolithic step-down switch

mode converter with built-in internal power

MOSFETs. It achieves 1.2A peak continuous

output current from a 2.7V to 6V input voltage

with excellent load and line regulation. The

output voltage can be regulated as low as 0.6V.

The

Constant-On-Time

control

scheme

provides fast transient response and eases loop

stabilization. Fault condition protection includes

cycle-by-cycle current limiting and thermal

shutdown.

The MP2160 is available in the small QFN8

1.5x2.0mm package and requires a minimum

number of readily available standard external

components.

The MP2160 is ideal for a wide range of

applications including High Performance DSPs,

FPGAs, PDAs, portable instruments and DVD

drivers.
