MP4561
1.5A, 2MHz, 55V
Step-Down Converter
The Future of Analog IC Technology
DESCRIPTION
The MP4561 is a high frequency step-down
switching regulator with integrated internal high-
side high voltage power MOSFET. It provides
1.5A output with current mode control for fast loop
response and easy compensation.
The wide 3.8V to 55V input range accommodates
a variety of step-down applications, including
those in 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 2MHz, the MP4561 is able to
prevent EMI (Electromagnetic Interference) noise
problems, such as those found in AM radio and
ADSL applications.
The MP4561 is available in small 3mm x 3mm
10-pin QFN with exposed pad package.
