MP2330H
24V, 3A, 1.2MHz,
Synchronous Buck Converter
DESCRIPTION
FEATURES
The MP2330H is a fully integrated, high-
frequency, synchronous, rectified, step-down,
switch-mode converter with internal power
MOSFETs. The MP2330H offers a very
compact solution that achieves 3A of
continuous output current with excellent load
and line regulation over a wide input range. The
MP2330H uses synchronous mode operation
for higher efficiency over the output current load
range.
Wide 4.2V to 24V Operating Input Range
75mΩ/40mΩ Low RDS(ON) Internal Power
MOSFETs
200µA Low IQ
High-Efficiency Synchronous Mode
Operation
Fast Load Transient Response
1.2MHz Switching Frequency
TON Extension
Forced PWM Operation
Programmable Soft-Start Time
Power Good (PG) Indication
Over-Current Protection (OCP) and Hiccup
Pre-Bias Start-Up
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.
