The MP2490 is a monolithic step-down switch mode converter with a programmable output current limit. It achieves 1.5A 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. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The MP2490 requires a minimum number of readily available standard external components. The MP2490 is available in QFN10 (3mm x 3mm), 8-pin SOIC and PDIP packages.
