MPQ4569

75V, 0.3A Synchronous Step-Down Converter AEC-Q100 Qualified

Datasheet

Description

The MPQ4569 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 5μA shutdown mode quiescent current in full temperature range 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 MPQ4569 is available in QFN-10 (3mmx3mm) and SOIC-8 EP packages.
