MP2259 Datasheet | Monolithic Power Systems

DESCRIPTION The MP2259 is a monolithic integrated stepdown switch mode converter with an internal power MOSFET. It achieves 1A continuous 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 MP2259 requires a minimum number of readily available standard external ponents. The MP2259 is available in TSOT23-6 and SOT23-6 packages. 1A, 16V, 1.4MHz Step-Down Converter FEATURES - 1A Output Current - 0.5Ω Internal Power MOSFET Switch - Stable with Low ESR Output Ceramic Capacitors - Up to 92% Efficiency - 0.1μA Shutdown Mode - Fixed 1.4MHz Frequency - Thermal Shutdown - Cycle-by-Cycle Over Current Protection - Wide 4.5V to 16V Operating Input Range - Output Adjustable from 0.81V to 14V - Available in TSOT23-6 and SOT23-6 Packages APPLICATIONS - Hand Disk Drive - x DSL Modems Cable - Set-Top Box For MPS green status, please visit MPS website under Quality Assurance “MPS” and “The Future of Analog IC Technology” are Registered Trademarks of Monolithic Power Systems, Inc.
