MP4569

75V, 0.3A Synchronous

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

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.

•

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.

Adjustable Output

1V Reference Voltage Output for QFN

Package

The wide 4.5V to 75V input range

accommodates

variety of step-down

•

applications in automotive environment. A

3.5μA shutdown mode quiescent current is

good for battery-powered applications.

•

Low Shutdown Mode Current: 3.5μA

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.

APPLICATIONS

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.
