DESCRIPTION

The MP2467 is a high frequency step-down

switching regulator with integrated internal

high-side, high voltage power MOSFET. It

provides 2.5A output with current mode control

for fast loop response and easy compensation.

The wide 6V to 36V input range accommodates

a variety of step-down applications, including

those

in

automotive

systems.

A

100µA

operational quiescent current allows use in

battery-powered applications.

High power conversion efficiency over a wide

load range is achieved by scaling down the

switching frequency at light load condition to

reduce the switching and gate driving losses.

The frequency foldback prevents inductor

current runaway during startup and thermal

shutdown

provides

reliable,

fault

tolerant

operation.

The MP2467 is available in thermally enhanced

SOIC8 package.
