MP3209 Datasheet, PDF (1/11 Pages) Monolithic Power Systems – 1.4MHz, 350mA Boost Converter

The Future of Analog IC Technology
DESCRIPTION
The MP3209 is a current mode step up
converter intended for small, low power
applications. The MP3209 switches at 1.4MHz
and allows the use of tiny, low cost inductor and
capacitor to achieve a solution less than 1mm
in height. Internal soft start results in small
inrush current and extends battery life.
The MP3209 includes under-voltage lockout,
current limiting, and thermal overload protection
to prevent damage in the event of an output
overload. The MP3209 is available in small
5-pin TSOT23 and 2mm x 2mm ultra-thin QFN
8-pin packages.
