MPQ3431C

21A, High-Efficiency, Fully Integrated,

Synchronous Boost Converter with

Configurable Peak Switching Current Limit,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ3431C is a 450kHz, fixed-frequency,

highly integrated boost converter with a wide

input voltage (V_IN) range. The MPQ3431C starts

from a V_INas low as 2.7V, and supports up to

20W of load power from a single-cell battery

•

Guaranteed Industrial/Automotive Temp

2.7V to 13V Start-Up Voltage

0.8V to 13V Operating Voltage

Up to 16V Output Voltage (V_OUT

)

Supports 20W Average Power Load and

40W Peak Power Load from 3.3V

Configurable Peak Switching Current Limit

Integrated 6mΩ and 9.5mΩ Power

MOSFETs

95% Efficiency for 3.6V V_INto 9V/3A

Selectable PSM, >23kHz USM, and FCCM

under Light-Load Conditions

450kHz Fixed Switching Frequency (f_SW)

Adaptive COT for Fast Transient Response

External Soft Start and Compensation Pins

Configurable UVLO and Hysteresis

175°C Over-Temperature Protection (OTP)

Available in a QFN-13 (3mmx4mm)

Package

with integrated, low on resistance (R_DS(ON)

power MOSFETs.

)

•

The MPQ3431C adopts constant-off-time

(COT) control topology, which provides fast

transient response. The MODE pin allows the

user to select pulse-skip mode (PSM), forced

continuous conduction mode (FCCM), or

ultrasonic mode (USM) under light-load

conditions. The configurable current limit

provides accurate overload protection. The low-

side MOSFET (LS-FET) limits the cycle-by-

cycle inductor peak current, and the high-side

MOSFET (HS-FET) eliminates the requirement

for an external Schottky diode.

•

Available in AEC-Q100 Grade 1

Full protection features include configurable

input under-voltage lockout (UVLO) and over-

temperature protection (OTP).

APPLICATIONS

•

Automotive Boost

Super Capacitors

Backup Batteries

The MPQ3431C is available in a QFN-13

(3mmx4mm) package.
