Description

General part information

MP24943 Series

The MP24943 is a monolithic, step-down, switch-mode converter. It supplies 3A of continuous output current over a wide inputsupply range with excellent load and line regulation. MP24943 achieves low EMI signature with wellcontrolled 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 readilyavailable standard external components. It is available in SOIC8 and SOIC8E package.Wide 4.5V to 55V Operating Input Range Programmable Output Over-Voltage Protection Output Adjustable from 0.8V to 45V 0.15? Internal Power MOSFET Switch Stable with Low ESR Output Ceramic Capacitors Fixed 100kHz Frequency Low EMI Signature Thermal Shutdown Cycle-by-Cycle Over-Current Protection Available in SOIC8 and SOIC8E Packages
