The Future of Analog IC Technology
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.
