MP2330C
24V, 3A, 650kHz,
Synchronous Step-Down Converter
with PG, SS, and Forced CCM in
SOT583 (1.6x2.1mm) Package
DESCRIPTION
The MP2330C is a fully integrated high-
frequency, synchronous, rectified, step-down,
switch-mode converter with internal power
MOSFETs. The MP2330C offers a very
compact solution that achieves 3A of
continuous output current with excellent load
and line regulation over a wide input range. The
MP2330C 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 MP2330C requires a minimal number of
readily available, standard, external
components and is available in a space-saving
SOT583 package
