MPQ4316

45V, 6A, Low I_Q, Synchronous Step-Down

Converter with Frequency Spread Spectrum,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ4316 is a frequency-configurable,

synchronous, step-down switching converter

with integrated internal high-side and low-side

power MOSFETs. The device provides 6A (or

less) of highly efficient output current with current

mode control for fast loop response.



Wide 3.3V to 45V Operating Voltage Range

6A of Continuous Output Current

1.7μA Low Shutdown Supply Current

18μA Sleep Mode Quiescent Current

Internal 48mΩ High-Side MOSFET and

20mΩ Low-Side MOSFET



350kHz to 1000kHz Configurable Switching

Frequency for Car Battery Applications

Can Be Synchronized to External Clock

Out-of-Phase Synchronized Clock Output

Fixed Output Options: 3.3V, 5V

Frequency Spread Spectrum (FSS) for Low

EMI

Symmetric V_INfor Low EMI

Power Good Output

External Soft Start

100ns Minimum On Time

The wide 3.3V to 45V input range

accommodates

variety of step-down



applications in automotive input environments. A

1.7μA shutdown mode quiescent current allows

the device to be used in battery-powered

applications.

The device achieves high power conversion

efficiency across the wide load range by scaling

down the switching frequency under light-load

conditions to reduce the switching and gate

driving losses.



Selectable Advanced Asynchronous Mode

(AAM) or Forced Continuous Conduction

Mode (FCCM)

An open drain power good signal indicates when

the output is within 95% to 105% of its nominal

voltage.



Low-Dropout Mode

Frequency foldback helps prevent inductor

current runaway during start-up. Thermal

shutdown provides reliable, fault-tolerant

operation.

Hiccup Over-Current Protection (OCP)

Available in a QFN-20 (4mmx4mm)

Package

Available in a Wettable Flank Package

Available in AEC-Q100 Grade 1



The device provides a high duty cycle and low-

dropout mode for automotive cold-crank

conditions.

APPLICATIONS



Automotive Infotainment

Automotive Clusters

Advanced Driver Assistance Systems
