TM MP2359 1.2A, 24V, 1.4MHz Step-Down Converter in a TSOT23-6 The Future of Analog IC Technology TM DESCRIPTION The MP2359 is a monolithic step-down switch mode converter with a built-in power MOSFET. It achieves 1.2A peak output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The MP2359 requires a minimum number of readily available standard external components. The MP2359 is available in TSOT23-6 and SOT23-6 packages. FEATURES 1.2A Peak Output Current 0.35 Internal Power MOSFET Switch Stable with Low ESR Output Ceramic Capacitors Up to 92% Efficiency 0.1A Shutdown Mode Fixed 1.4MHz Frequency Thermal Shutdown Cycle-by-Cycle Over Current Protection Wide 4.5V to 24V Operating Input Range Output Adjustable from 0.81V to 15V Available in TSOT23-6 and SOT23-6 Packages Distributed Power Systems Battery Charger Pre-Regulator for Linear Regulators WLED Drivers EVALUATION BOARD REFERENCE Board Number EV2359DJ-00B Dimensions 2.1”X x 1.9”Y x 0.4”Z APPLICATIONS “MPS” and “The Future of Analog IC Technology” are Trademarks of Monolithic Power Systems, Inc.
