MPQ4430

36V, 3.5A, Low Quiescent Current,

Synchronous, Step-Down Converter

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ4430 is a frequency-programmable

(350kHz to 2.5MHz), synchronous, step-down,

switching regulator with integrated internal high-

side and low-side power MOSFETs. It provides

up to 3.5A of highly efficient output current with

current mode control for fast loop response.



Wide 3.3V to 36V Operating Input Range

3.5A Continuous Output Current

1μA Low Shutdown Mode Current

10μA Sleep Mode Quiescent Current

Internal 90mΩ High-Side and 40mΩ Low-

Side MOSFETs



350kHz to 2.5MHz Programmable

Switching Frequency

Fixed Output Options: 3.3V, 3.8V, 5V

Synchronize to External Clock

Selectable In-Phase or 180° Out-of-Phase

Power Good (PG) Indicator

Programmable Soft-Start (SS) Time

80ns Minimum On Time

Selectable Forced CCM or AAM

Low Dropout Mode

Over-Current Protection (OCP) with Valley-

Current Detection and Hiccup

Available in a QFN-16 (3mmx4mm)

Package

Available with Wettable Flank

AEC-Q100 Grade 1

The wide 3.3V to 36V input range accommodates

a variety of step-down applications in automotive

input environments and is ideal for battery-

powered applications due to its extremely low

quiescent current.



The

MPQ4430

employs

advanced

asynchronous mode (AAM), which helps

achieve high efficiency in light-load condition by

scaling down the switching frequency to reduce

switching and gate driving losses.

Standard features include soft start (SS),

external clock synchronization, enable (EN)

control, and a power good (PG) indicator. High-

duty cycle and low dropout mode are provided

for automotive cold-crank condition.



Over-current protection (OCP) with valley-

current detection is employed to prevent the

inductor current from running away. Hiccup

mode reduces the average current in short-

circuit condition greatly. Thermal shutdown

provides reliable and fault-tolerant operation.
