DESCRIPTION

The MPQ4560 is a high-frequency, step-down,

switching regulator with an integrated, high-

side, high-voltage, power MOSFET. It provides

a 2A output with current mode control for fast

loop response and easy compensation.

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

allows

use

in

battery-powered

applications.

High-power conversion efficiency over a wide

load range is achieved by scaling down the

switching frequency in light load conditions to

reduce the switching and gate driving losses.

Frequency foldback prevents inductor current

runaway during startup and thermal shutdown

provides reliable, fault tolerant operation.

By switching at 2MHz, the MPQ4560 can

prevent electromagnetic interference problems,

such as those found in AM radio and ADSL

applications.

The MPQ4560 is available in small 3mm x 3mm

QFN10 and SOIC8E packages.
