Description

The MP2459 is a monolithic, step,down, switch,mode 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 components. The MP2459 is available in a TSOT23,6 package.
