75mΩ/40mΩ Low RDS(ON) Internal Power
MOSFETs
200µA Low IQ
High-Efficiency Synchronous Mode
Operation
Fast Load Transient Response
650kHz Switching Frequency
Forced PWM Operation
Programmable Soft-Start Time
Power Good (PG) Indication
Over-Current Protection (OCP) and Hiccup
Pre-Bias Start-Up
Thermal Shutdown
Available in a SOT583 (1.6mmx2.1mm)
Package
MOSFETs. The MP2333C offers
a
very
compact solution that achieves 3A of
continuous output current with excellent load
and line regulation over a wide input range. The
MP2333C 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.
APPLICATIONS
The MP2333C requires a minimal number of
