MP2499AGQB-Z Monolithic Power Systems

MP2499A 36V, 3A Max, High-Efficiency, Synchronous, Step-Down Converter with Output Line Drop Compensation DESCRIPTION FEATURES The MP2499A is a synchronous, rectified, step- Wide 5V to 36V Continuous Operating Input down, switch-mode converter with built-in Range power MOSFETs. The MP2499A offers a very 85m/55m Low R Internal Power DS(ON) compact solution that achieves a maximum of MOSFETs 3A of continuous output current with built-in, High-Efficiency Synchronous Mode output, line drop compensation. Operation Default 270kHz Switching Frequency The MP2499A uses synchronous mode Synchronizes to a 200kHz to 2.4MHz operation to achieve high efficiency over the External Clock output current load range. Current-mode Internal Soft Start operation provides fast transient response and Output Line Drop Compensation eases loop stabilization. Accurate Continuous Output Current Limit Full protection features include over-current with External Resistor protection (OCP) and thermal shutdown. Over-Current Protection (OCP) and Hiccup The MP2499A requires a minimal number of Thermal Shutdown readily available, standard, external Output Adjustable from 0.8V components and is available in a space-saving Available in a QFN-13 (2.5mmx3mm) QFN-13 (2.5mmx3mm) package.
