DESCRIPTION

The MP4571 is a fully integrated, fixedfrequency,

synchronous step-down converter. It

can achieve up to 1A of continuous output

current with peak current control for excellent

transient response.

The wide 4.5V to 60V input voltage range

accommodates a variety of step-down

applications in an automotive input environment.

A 2μA shutdown mode quiescent current makes

it ideal for battery-powered applications.

The MP4571 integrates internal high-side and

low-side power MOSFETs for high efficiency

without an external Schottky diode, and is

available in a 12-pin QFN package.

The MP4571 employs advanced asynchronous

modulation (AAM), which achieves high efficiency

during light load by scaling down the frequency to

reduce the switching and gate driver losses.

The MP4571 offers standard features including

built-in soft start, enable control, and a power

good indicator. High duty cycle and low-dropout

mode are provided for automotive cold crank

conditions. In addition, the chip provides overcurrent

protection with valley current detection,

which helps prevent current runaway. It also has

hiccup short-circuit protection (SCP), input undervoltage

lockout (UVLO), and auto-recovery

thermal protection.

With internal compensation, the MP4571 offers

a very compact solution with a minimum number

of readily available, standard external

components. It is available in a QFN-12

(2.5mmx3mm) package.
