MP4462

3.5A, 4MHz, 36V

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP4462 is a high frequency step-down

switching regulator with an integrated internal

high-side high voltage power MOSFET. It

provides 3.5A output with current mode control for

fast loop response and easy compensation.

•

120μA Quiescent Current

Wide 3.8V to 36V Operating Input Range

150mΩ Internal Power MOSFET

Up to 4MHz Programmable Switching

Frequency

•

Ceramic Capacitor Stable

Internal Soft-Start

Internally Set Current Limit without a

Current Sensing Resistor

Output Adjustable from 0.8V to 30V

Available in 3x3mm QFN10 and SOIC8E

Packages.

The wide 3.8V to 36V input range accommodates

a variety of step-down applications, including

those in an automotive input environment. A

120µA operational quiescent current allows use in

battery-powered applications.

•

High power conversion efficiency over a wide

load range is achieved by scaling down the

switching frequency at light load condition to

reduce the switching and gate driving losses.

APPLICATIONS

•

High Voltage Power Conversion

Automotive Systems

Industrial Power Systems

Distributed Power Systems

Battery Powered Systems

The frequency foldback helps prevent inductor

current runaway during startup and thermal

shutdown provides reliable, fault tolerant

operation.

In some applications, such as AM radio and

ADSL applications, in which the device is

sensitive to frequency band, the MP4462 can

avoid the related EMI problem by setting the

frequency at 4MHz.

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

status, please visit MPS website under Products, Quality Assurance page.
