MPQ3425

3A, 55V Boost Converter with

Programmable Switching Frequency,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ3425 is a current control mode,

step-up converter with a 3.5A, 90mΩ internal

MOSFET that provides fast transient response.

It operates with an input voltage as low as 3.1V,

and can generate up to 55V.

•

Wide 3.1V to 22V BIAS Supply Voltage

Range

Wide 3V to 50V Input Voltage Range

3.5A, 90mΩ, Power MOSFET

Output Voltage up to 55V

Programmable 300kHz to 2MHz f_SW

Programmable Under-Voltage Lockout

(UVLO), Soft Start, UVLO Hysteresis

Micropower Shutdown <1μA

Thermal Shutdown OTP (160°C)

Available in QFN-14 (3mmx4mm) and QFN-

14 (4mmx4mm) Packages

•

The MPQ3425 features

configurable

switching frequency of up to 2MHz for easy

filtering and low noise. An external

compensation pin allows the user to flexibly set

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.

•

QFN-14 (4mmx4mm) Package Is Available

in a Wettable Flank Package

Available in AEC-Q100 Grade 1

Full protection features include under-voltage

lockout (UVLO), current limiting, and thermal

shutdown.

APPLICATIONS

The MPQ3425 is available in low-profile QFN-

14 (3mmx4mm) and QFN-14 (4mmx4mm)

packages with an exposed pad. The QFN-14

(4mmx4mm) package is available in a wettable

flank package.
