Product 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, cycle­by­cycle current limit, and thermal shutdown.   MP24943 requires a minimal number of readily-available standard external components. It is available in SOIC8 and SOIC8E package.
