Features: MP2332C 18V, 2A, 650kHz, Synchronous Ste p-Down Converter with PG, SS, and Force d CCM DESCRIPTION The MP2332C is a ful ly integrated, highfrequency, synchrono us, rectified, step-down, switch-mode c onverter with internal power MOSFETs. T he MP2332C offers a very compact soluti on that achieves 2A of continuous outpu t current with excellent load and line regulation over a wide input range. The MP2332C uses synchronous mode operatio n for higher efficiency over the output current load range. Constant-on-time ( COT) control operation provides very fa st transient response, easy loop design , and very tight output regulation. Ful l protection features include short-cir cuit protection (SCP), over-current pro tection (OCP), under-voltage protection (UVP), and thermal shutdown. The MP233 2C requires a minimal number of readily available, standard, external componen ts and is available in a space-saving S OT583 package. TYPICAL APPLICATION FEA TURES  Wide 4.2V to 18V Operating Input Range  95mΩ/45mΩ Low .

MP2332C
18V, 2A, 650kHz,
Synchronous Step-Down Converter
with PG, SS, and Forced CCM
DESCRIPTION
The MP2332C is a fully integrated, high-
frequency, synchronous, rectified, step-down,
switch-mode converter with internal power
MOSFETs. The MP2332C offers a very
compact solution that achieves 2A of
continuous output current with excellent load
and line regulation over a wide input range. The
MP2332C 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 MP2332C requires a minimal number of
readily available, standard, external
components and is available in a space-saving
SOT583 package.
