MP2492DN-LF-Z

The MP2492 is a monolithic step-down switch mode converter with a programmable output current limit. It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation. The maximum output current can be programmed by sensing current through the inductor DC resistance (DCR) or an accurate sense resistor. MP2492 achieves low EMI signature with well controlled switching edges. Fault condition protection includes cycle-by-cycle current limiting, and thermal shutdown. The MP2492 requires a minimum number of readily available standard external components. The MP2492 is available in QFN10 (3mm x 3mm) and SOIC8E packages.
