DESCRIPTION

The MP9162A is a monolithic, step-down,

switch-mode converter with built-in, internal

power MOSFETs. It can achieve 2A of

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 (COT) control scheme

provides a fast transient response and eases

loop stabilization. Fault condition protections

include cycle-by-cycle current limiting and

thermal shutdown.

The MP9162A is available in a small QFN-8

(2.0mmx1.5mm) package and requires only a

minimal number of readily available, standard,

external components.

The MP9162A is ideal for a wide range of

applications, including high-performance DSPs,

FPGAs, PDAs, and portable instruments.
