MP2259 Datasheet | Monolithic Power Systems

The Future of Analog IC Technology 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.
