DESCRIPTION
The EV3427-L-00A Evaluation Board is
designed to demonstrate the performances of
MPS’ MP3427, which can provide 30W load
from Li-on battery input.
The MP3427 is a 600 kHz fixed frequency, high
efficiency, wide input range, current mode boost
converter with optional internal or external
current sensing configuration for high
integration or high power application. It features
internally a 10m power switch and a
synchronous gate driver for high conversion
efficiency. The MP3427 is available in a low
profile 22-pin 3mmx4mm QFN package.
This board is configured for 8V/30W application.
