MP92265
18V, 5A, 500kHz, High-Efficiency,
Synchronous, Step-Down Converter
in 8-Pin TSOT23
DESCRIPTION
FEATURES
The
MP92265
is
a
high-frequency,
Wide 6V to 18V Operating Input Range
Adjustable Output Voltage as Low as 0.6V
Low 47mΩ/18mΩ RDS(ON) of Internal Power
MOSFETs
synchronous, rectified, step-down, switch-mode
converter with built-in power MOSFETs. The
MP92265 offers a very compact solution that
achieves 5A of output current with excellent
load and line regulation over a wide input
supply range.
High Efficiency up to 97%
Fixed 500kHz Switching Frequency
External Programmable Soft-Start Time
1% Reference Accuracy at Room
Temperature
External Programmable AAM Power-Save
Mode
Over-Current Protection (OCP) with Hiccup
Mode
Available in a TSOT23-8 Package
The MP92265 uses synchronous mode
operation to achieve high efficiency over the
output current load range. Current-mode
operation provides fast transient response and
eases loop stabilization.
Full protection features include over-current
protection (OCP) and thermal shutdown.
APPLICATIONS
The MP92265 requires a minimal number of
readily
available,
standard,
external
Flat-Panel Televisions and Monitors
Notebook Systems and I/O Power
Digital Set-Top Boxes
components and is available in a space-saving,
8-pin, TSOT23 package.
