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

condition

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.
