The Future of Analog IC Technology
DESCRIPTION
The MP2565 is a high frequency step-down
switching regulator with an 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 4.5V to 50V input range accommodates
a variety of step-down applications, including
those in an automotive input environment. A 12µA
shutdown mode supply 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 helps prevent inductor
current runaway during startup and thermal
shutdown provides reliable, fault tolerant
operation.
By switching at 4MHz, the MP2565 is able to
prevent EMI (Electromagnetic Interference) noise
problems, such as those found in AM radio and
ADSL applications.
The MP2565 is available in small 3mm x 3mm
QFN10 and thermally enhanced SOIC8 packages.
