Synchronous, Step-Down Converter
The Future of Analog IC Technology
DESCRIPTION
FEATURES
Wide 4.5V to 24V Operating Input Range
90mΩ/40mΩ Low RDS(ON) Internal Power
MOSFETs
The
synchronous, rectified, step-down, switch-mode
converter with built-in, internal power
MP92325
is
a
high-frequency,
Low Quiescent Current
High-Efficiency Synchronous Mode
Operation
Fixed 500kHz Switching Frequency
Frequency Sync from 200kHz to 2MHz
External Clock
MOSFETs. It offers a very compact solution
that achieves 3A of continuous output current
with excellent load and line regulation over a
wide input supply range. The MP92325 uses
synchronous mode operation for higher
efficiency over the output current load range.
Power Save Mode at Light Load
Internal Soft Start
Power Good Indicator
Over-Current Protection (OCP) and Hiccup
Thermal Shutdown
Output Adjustable from 0.8V
Available in an 8-Pin TSOT-23 Package
Current-mode operation provides
transient response and eases loop stabilization.
a
fast
Full protection features include over-current
protection (OCP) and thermal shutdown.
The MP92325 requires a minimum number of
readily
available,
standard,
external
components and is available in a space-saving,
8-pin TSOT23 package.
