MP2332H

4.2 - 18V Input, 2A, 1.2MHz

Synchronous Buck Converter

with Power Good and Soft Start

in SOT583 (1.6x2.1mm) Package

DESCRIPTION

FEATURES

The MP2332H is a fully integrated, high-

frequency, synchronous, rectified, step-down,

switch-mode converter with internal power



Wide 4.2V to 18V Operating Input Range

MOSFETs. The MP2332H offers

very



compact solution that achieves 2A of

continuous output current with excellent load

and line regulation over a wide input range. The

MP2332H uses synchronous mode operation

for higher efficiency over the output current load

range.



Fast Load Transient Response

1.2MHz Switching Frequency

_ONExtension

Forced PWM Operation

Constant-on-time (COT) control operation

provides very fast transient response, easy loop

design, and very tight output regulation.

Programmable Soft-Start Time

Power Good (PG) Indication

Over-Current Protection (OCP) and Hiccup

Pre-Bias Start-Up

Thermal Shutdown

Available in a SOT583 (1.6mmx2.1mm)

Package

Full protection features include short-circuit

protection (SCP), over-current protection (OCP),

under-voltage protection (UVP), and thermal

shutdown.
