MP3426  
6A, 35V Boost Converter with  
Programmable Switching Frequency  
and UVLO  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP3426 is a current-mode step-up  
converter with a 6A, 90minternal switch that  
provides a highly efficient regulator with a fast  
6A, 90m, 45V Power MOSFET  
Uses Very Small Capacitors and Inductors  
Wide Input Range: 3.2V to 22V  
Output Voltage as High as 35V  
Programmable fsw: 300kHz to 2MHz  
Programmable UVLO, Soft-Start, UVLO  
Hysteresis  
Micropower Shutdown <1μA  
Thermal Shutdown 160°C  
Available in 14-Pin 3mm×4mm QFN  
Package  
response.  
The  
MP3426  
features  
a
programmable frequency of up to 2MHz that  
allows for easy filtering and reduces noise. An  
external compensation pin gives the user  
flexibility in setting loop dynamics, and uses  
small, low-ESR, ceramic output capacitors.  
Soft-start results in a small inrush current and  
can be programmed with an external capacitor.  
The MP3426 operates from an input voltage as  
low as 3.2V and can generate up to a 35V  
output.  
APPLICATIONS  
Telecom—Power Supplies  
Audio—Microphone and Tuner Bias  
Automotive  
The MP3426’s features include under-voltage  
lockout, current limiting, and thermal overload  
protection. The MP3426 is available in a low-  
profile 14-pin 3mm×4mm QFN package with an  
exposed pad.  
All MPS parts are lead-free, halogen free, and adhere to the RoHS  
directive. For MPS green status, please visit MPS website under Quality  
Assurance.
