MPQ4436/4436A

45V, 6A, Low I_Q,

Synchronous Step-Down Converter,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The

programmable,

switching regulator with integrated internal high-

side and low-side power MOSFETs. It provides

6A (or less) of highly efficient output, with current

mode control for fast loop response.

•

Wide 3.3V to 45V Operating Voltage Range

6A Continuous Output Current

1.7μA Low Shutdown Supply Current

18μA Sleep Mode Quiescent Current

Internal 48mΩ High-Side and 20mΩ Low-

Side MOSFET

•

350kHz to 1000kHz Programmable

Switching Frequency for Car Battery

Applications

Synchronize to External Clock

Multi-Phase Capability

Out-of-Phase Synchronized Clock Output

Frequency Spread Spectrum (FSS) Option

for Low EMI

MPQ4436: Non-FSS version

MPQ4436A: FSS version

The wide 3.3V to 45V input range

accommodates

variety of step-down

applications in an automotive input environment.

A 1.7μA shutdown mode quiescent current

allows the part to be used 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.

•

Symmetric V_INfor Low EMI

Power Good Output

External Soft Start

An open-drain power good signal indicates that

the output is within 93% to 106% of its nominal

voltage.

100ns Minimum On Time

Frequency foldback helps prevent inductor

current runaway during start-up. Thermal

shutdown provides reliable, fault-tolerant

operation.

Selectable Advanced Asynchronous Mode

(AAM) or Forced Continuous Conduction

Mode (FCCM)

•

Low Dropout Mode

Hiccup Over-Current Protection

Available in a QFN-20 (4mmx4mm)

Package

Available in a Wettable Flank Package

Available in AEC-Q100 Grade-1

High-duty cycle and low dropout mode are

provided for the automotive cold crank condition.

The MPQ4436/4436A is available in a QFN-20

(4mmx4mm) package.
