MPQ3425-AEC1

3A, 55V Boost Converter with

Programmable Switching Frequency,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ3425 is a current-mode, step-up

converter with a 3.5A, 90mΩ internal switch that

provides a highly efficient regulator with fast

•

Guaranteed Industrial and Automotive

Temp Range Limits

3.5A, 90mΩ, 55V Power MOSFET

Uses Small Capacitors and Inductors

Wide Input Range: 3.1V to 22V

Output Voltage up to 55V

Programmable F_SW: 300kHz - 2MHz

Programmable Under-Voltage Lockout

(UVLO), Soft-Start, UVLO Hysteresis

response.

The

MPQ3425

features

programmed frequency of up to 2MHz that

provides easy filtering and low noise. An

external compensation pin allows for flexibility

in setting loop dynamics and operates with

small, low ESR ceramic output capacitors. The

soft-start feature provides a small inrush current

and can be programmed with an external

capacitor. The MPQ3425 operates with an input

voltage as low as 3.1V and can generate 48V at

up to 350mA from a 12V supply.

•

Available in a QFN-14 (3mmx4mm)

Package

AEC-Q100 Qualified Grade 1

•

Full protection features include under-voltage

lockout (UVLO), current limiting, and thermal

overload protection. The MPQ3425 is available

in a low-profile QFN-14 (3mmx4mm) package

with an exposed pad.

APPLICATIONS

•

Telecom and Power Supplies

Microphones and Tuner Bias
