MPQ3432

21A, High-Efficiency, Fully Integrated,

Synchronous Boost Converter with

Configurable Current Limit,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ3432 is 600kHz, fixed-frequency,

highly integrated boost converter with a wide

input range. The MPQ3432 starts up from an

input voltage (V_IN) as low as 2.7V, and supports

up to 20W of load power from a single-cell

battery with integrated low R_DS(ON)power

MOSFETs.

2.7V to 13V Start-Up Voltage (V_ST)

0.8V to 13V Operation Input Voltage (V_IN)

•

Up to 16V Output Voltage (V_OUT

)

Supports 20W Average Power Load and

40W Peak Power Load from 3.3V

Configurable Switch Peak Current Limit

600kHz Fixed Switching Frequency (f_SW)

Adaptive Constant-Off-Time (COT) Control

for Fast Transient Response

External Soft Start and Compensation Pins

Configurable Under-Voltage Lockout

(UVLO) and Hysteresis

175°C Over-Temperature Protection (OTP)

Available in a QFN-13 (3mmx4mm)

Package

•

The MPQ3432 adopts constant-off-time (COT)

control to provide 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 need for an

external Schottky diode.

•

Full protection features include configurable

input under-voltage lockout (UVLO) and over-

temperature protection (OTP).

•

The MPQ3432 is available in a QFN-13

(3mmx4mm) package.

•

Available in AEC-Q100 Grade 1

APPLICATIONS

•

Automotive Boost

Super Capacitors

Backup Batteries
