MP24943
3A, 55V, 100kHz Step-Down Converter
with Programmable Output OVP Threshold
The Future of Analog IC Technology
DESCRIPTION
The MP24943 is a monolithic, step-down,
switch-mode converter. It supplies 3A of
continuous output current over a wide input-
supply range with excellent load and line
regulation.
MP24943 achieves low EMI signature with well-
controlled switching edges.
Fault

protection
includes
programmable-output over-voltage protection,
cycle-by-cycle current limit, and thermal
shutdown.
MP24943 requires a minimal number of readily-
available standard external components. It is
available in SOIC8 and SOIC8E package.
