MP4568

60V, 100mA Synchronous

Step-Down Converter

FEATURES

DESCRIPTION



20μA Quiescent Current

Wide 4.5V to 45V Operating Range with 50V

Input OVP

The MP4568 is a high-frequency, step-down,

switching regulator with integrated high-

side/low-side, high-voltage power MOSFETs. It

provides a highly efficient output of up to

100mA.



60V Integrated MOSFETs with 0.7Ω and

2.25Ω Ron



Programmable Switching Frequency

Stable with Ceramic Output Capacitors

Low Output Ripple

60V rated MOSFETs and 4.5V to 45V operation

range accommodates a variety of step-down

applications in automotive input environment. A

5μA shutdown mode quiescent current allows

use in battery-powered applications.

Programmable Soft-Start

Adjustable Input UVLO Hysteresis

Precision Peak Current Limit without

Current-Sensing Resistor

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.



Programmable Peak Current Limit

>90% Efficiency at 10V VIN to 5V V_OUT/2mA

1.0V Feedback Reference Voltage

Low Shutdown Mode Current: <5μA

3mmx3mm QFN10 Package

The switching frequency during start-up and

short circuit also can be scaled down to helps

prevent inductor current runaway. Thermal

shutdown provides reliable, fault-tolerant

operation.

APPLICATIONS



4mA to 20mA Current Loops

Automotive Systems

Industrial Power Systems

Distributed Power Systems

Battery Powered Systems

The MP4568 is available in a 3mmx3mm

QFN10 package.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green
