MPQ4317

45V, 7A, Low I_Q, Synchronous Step-Down

Converter with Frequency Spread Spectrum,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ4317 is a configurable-frequency,

synchronous, step-down switching regulator with

integrated internal high-side and low-side power

MOSFETs. It provides up to 7A of highly efficient

output current (I_OUT) with current mode control for

fast loop response.



Wide 3.3V to 45V Operating V_INRange

7A Continuous Output Current (I_OUT

)

1.7μA Low Shutdown Supply Current

18μA Sleep Mode Quiescent Current

Internal 48mΩ High-Side MOSFET (HS-

FET) and 20mΩ Low-Side MOSFET (LS-

FET)

350kHz to 1000kHz Configurable Switching

Frequency (f_SW) for Car Battery Applications

Can Be Synchronized to an 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 (PG) Output

External Soft Start (SS)

100ns Minimum On Time

Selectable Advanced Asynchronous

Modulation (AAM) Mode or Forced

Continuous Conduction Mode (FCCM)

Low-Dropout Mode

Over-Current Protection (OCP) with Hiccup

Mode

The wide 3.3V to 45V input voltage (V_IN) range



accommodates

variety of step-down

applications in automotive input environment. A

1.7μA shutdown mode quiescent current allows

use in battery-powered applications.



High power conversion efficiency across a wide

load range is achieved by scaling down the

switching frequency (f_SW) under light-load

conditions to reduce switching and gate driver

losses.



An open-drain power good signal indicates

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

nominal voltage.

Frequency foldback helps prevent inductor

current (I_L) runaway during start-up. Thermal

shutdown provides reliable, fault-tolerant

operation. High duty cycle and low-dropout

mode are provided for automotive cold-crank

conditions.



Available in a QFN-20 (4mmx4mm)

Package



Available in a Wettable Flank Package

Available in AEC-Q100 Grade 1

The MPQ4317 is available in a QFN-20
