Overview
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.
