MP3425

3A, 55V Boost Converter with

Programmable Switching Frequency

and UVLO

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP3425 is a current mode step-up

converter with a 3.5A, 90mΩ internal switch to

provide a highly efficient regulator with fast

response. The MP3425 features a programmed

frequency up to 2MHz allowing for easy filtering

and low noise. An external compensation pin

gives the user flexibility in setting loop dynamics,

and operates with small, low-ESR ceramic

output capacitors. Soft-start results in small

inrush current and can be programmed with an

external capacitor. The MP3425 operates from

an input voltage as low as 3.1V and can

generate 48V at up to 350mA from a 12V

supply.
