MPQ4561-AEC1

1.5A, 2MHz, 55V

Step-Down Converter

Available in AEC-Q100

DESCRIPTION

FEATURES

The MPQ4561 is a high-frequency, step-down,

switching regulator with an integrated internal

high-side high voltage power MOSFET. It

provides up to a 1.5A output with current mode

control for fast loop response and easy

compensation.



Guaranteed Industrial/Automotive

Temperature Range Limits

Wide 3.8V to 55V Operating Input Range

300mΩ Internal Power MOSFET

Up to 2MHz Programmable Switching

Frequency



140μA Quiescent Current

Stable with Ceramic Capacitor

External Soft-Start

The wide 3.8V-to-55V input range accommodates

a variety of step-down applications, including

those in automotive input environment. A 12µA

shutdown mode supply current makes it suitable

for battery-powered applications.

Up to 95% Efficiency

Output Adjustable from 0.8V to 52V

Available in QFN10 (3mmx3mm) package

AEC-Q100 Qualified

A scaled-down switching frequency in light-load

conditions provides high power-conversion

efficiency over a wide load range while reducing

switching and gate driver losses.

APPLICATIONS



High-Voltage Power Conversion

Automotive Systems

Industrial Power Systems

Distributed Power Systems

Battery Powered Systems

The frequency foldback prevents inductor current

runaway during startup and thermal shutdown

provides reliable, fault tolerant operation.

By switching at 2MHz, the MPQ4561 is able to

prevent EMI (Electromagnetic Interference) noise

problems, such as those found in AM radio and

ADSL applications.

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

status, please visit MPS website under Quality Assurance.
