MPQ3428A  
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 18mLow-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 18m, 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.
