MP2459GJ-Z

MP2459GJ-Z is a 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. Typical applications include power meters, distributed power systems, battery chargers, pre-regulators for linear regulators, and WLED drivers.
