The Future of Analog IC Technology
DESCRIPTION
The MP4569 is a step-down switching regulator
with integrated high-side/low-side, high-voltage
power MOSFETs. It provides a highly efficient
output of up to 0.3A.
The wide 4.5V to 75V input range
accommodates a variety of step-down
applications in automotive environment. A
3.5μA shutdown mode quiescent current is
good for battery-powered applications.
It allows for high power conversion efficiency
over a wide load range by scaling down the
switching frequency under light-load condition
to reduce the switching and gate driver losses.
The switching frequency during start-up and
short circuit also can be scaled down to prevent
inductor current runaway. Thermal shutdown
provides reliable, fault-tolerant operation.
The MP4569 is available in QFN-10
(3mmx3mm) and SOIC-8 EP packages.
