DESCRIPTION

The MP2162 is a monolithic step-down switch

mode converter with built-in internal power

MOSFETs. It achieves 2A continuous output

current from a 2.5V 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 MP2162 is available in the small QFN8

2.0x1.5mm package and requires a minimum

number of readily available standard external

components.

The MP2162 is ideal for a wide range of

applications including High Performance DSPs,

FPGAs, PDAs, and portable instruments.
