MPQ3428A

19A, 600kHz, 20V Wide Input Range, Synchronous

Boost Converter with Input Disconnect Function,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

The MPQ3428A is an Automotive AECQ

application device with 600kHz, fixed-frequency,

high-efficiency, wide input range, current mode

boost converter, optional input disconnect and

an input average current limit function. The

input disconnect feature provides additional

protection by isolating the input from the output

during output short or shutdown.



Guaranteed Industrial/Automotive Temp

3V to 20V Wide Input Range

Integrated 18mΩ Low-Side Power FET

SDR Driver for Synchronous Solution

19A Internal Switch Current Limit or

External Programmable Input Current

Limit

Input Disconnect and Output SCP

External Soft Start and Compensation for

Higher Flexibility

Programmable UVLO and Hysteresis

<1µA Shutdown Current

Thermal Shutdown at 150°C

Available in a QFN-22 (3mmx4mm)

Package



With a programmable input average current

limit, the MPQ3428A supports a wide range of

applications, including eCall, Smart latch,

Telematics and infotainment. The MPQ3428A

features a 18mΩ, 24V power switch and a

synchronous gate driver for high efficiency. An

external compensation pin allows flexibility in

setting loop dynamics and obtaining optimal

transient performance under all conditions.



Available in AEC-Q100 Grade 1

APPLICATIONS

The MPQ3428A includes under-voltage lockout,

switching current limiting, and thermal

shutdown to prevent damage in the event of an

output overload. The MPQ3428A is available in

a low-profile QFN-22 (3mmx4mm) package.
