MP2459GJ Datasheet | Monolithic Power Systems

DESCRIPTION The MP2459 is a monolithic, step-down, switchmode converter with a built-in power MOSFET. It achieves a 0.5A peak-output current over a wide input supply range with excellent load and line regulation. Current-mode operation provides a fast transient response and eases loop stabilization. Fault condition protections include cycle-by-cycle current limiting and thermal shutdown. The MP2459 requires a minimal number of readily-available external ponents. The MP2459 is available in a TSOT23-6 package.
