2A, 55V, 100kHz Step-Down Converter



The MP2494 is a monolithic step-down switch mode converter. It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation. MP2494 achieves low EMI signature with well controlled switching edges. Fault condition protection includes cycle­by­cycle current limiting and thermal shutdown. The MP2494 requires a minimum number of readily available standard external components. The MP2494 is available in SOIC8 and SOIC8E package.
