MPQ4569-AEC1

75V, 0.3A Synchronous

Step-Down Converter

AEC-Q100 Qualified

FEATURES

DESCRIPTION



20μA Quiescent Current (Active mode)

Wide 4.5V to 75V Operating Input Range

1.2Ω/0.45Ω Internal Power MOSFETs

Programmable Soft-Start

FB-Tolerance: 1% at Room Temperature;

2% at Full Temperature.

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

variety of step-down



Adjustable Output Voltage

1V Reference Voltage Output for QFN

Package

applications in automotive environment. A 5μA

shutdown mode quiescent current in full

temperature range is good for battery-powered

applications.



Low Shutdown Mode Current: 5μA

Available in QFN-10 (3mmx3mm) and

SOIC-8 EP Packages

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.



Available in AEC-Q100 Grade 1

APPLICATIONS



Automotive Systems

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.
