DESCRIPTION
The EV3428-L-00A Evaluation Board is
designed to demonstrate the performances of
MPS’ MP3428, which can provide 25W load
from 3.3V input.
The MP3428 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, 24V power switch and a
synchronous gate driver for high conversion
efficiency. The MP3428 is available in a low
profile 22-pin 3mmx4mm QFN package.
This board is configured for 12V application, the
maximum output current is determined by
current limit or permitted temperature
performance.
