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/40Low 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.  
Thermal Shutdown  
Available in a SOT583 (1.6mmx2.1mm)  
Package  
The MP2330H requires a minimal number of
