The MP2499MGQB-Z 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 MP2499MGQB-Z can survive high-voltage transients such as those found in automotive and industrial applications.The MP2499MGQB-Z requires a minimum number of readily available standard external components. The MP2499MGQB-Z is available in a 16-pin SOIC package. 9icnet Electronics is an authorized Monolithic Power Systems distributor.
