The MP2499 is a monolithic step-down switch mode converter with a programmable output current limit and an integrated input over-voltage protection switch. It achieves 2.0A 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 MP2499 can survive high-voltage transients such as those found in automotive and industrial applications. The MP2499 requires a minimum number of readily available standard external components. The MP2499 is available in a 16-pin SOIC package.
