Features: MP2333H 4.2 - 18V Input, 3A, 1.2MHz Sync hronous Buck Converter with Power Good and Soft Start in SOT583 (1.6x2mm) Pack age DESCRIPTION The MP2333H is a fully integrated, highfrequency, synchronous , rectified, step-down, switch-mode con verter with internal power MOSFETs. The MP2333H offers a very compact solution that achieves 3A of continuous output current with excellent load and line re gulation over a wide input range. The M P2333H uses synchronous mode operation for higher efficiency over the output c urrent load range. Constant-on-time (CO T) control operation provides very fast transient response, easy loop design, and very tight output regulation. Full protection features include short-circu it protection (SCP), over-current prote ction (OCP), under-voltage protection ( UVP), and thermal shutdown. The MP2333H requires a minimal number of readily a vailable, standard, external components and is available in a space-saving SOT 583 package TYPICAL APPLICATION FEATURES  Wide 4.2V to 18V Op.

MP2333H
4.2 - 18V Input, 3A, 1.2MHz
Synchronous Buck Converter
with Power Good and Soft Start
in SOT583 (1.6x2mm) Package
DESCRIPTION
The MP2333H is a fully integrated, high-
frequency, synchronous, rectified, step-down,
switch-mode converter with internal power
MOSFETs. The MP2333H offers a very
compact solution that achieves 3A of
continuous output current with excellent load
and line regulation over a wide input range. The
MP2333H uses synchronous mode operation
for higher efficiency over the output current load
range.
Constant-on-time (COT) control operation
provides very fast transient response, easy loop
design, and very tight output regulation.
Full protection features include short-circuit
protection (SCP), over-current protection (OCP),
under-voltage protection (UVP), and thermal
shutdown.
The MP2333H requires a minimal number of
readily available, standard, external
components and is available in a space-saving
SOT583 package
