MPQ2459 Datasheet (MPS) - Step-Down Converter

MPQ2459, Step-Down Converter

The MPQ2459 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.
