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 10mΩ, 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.
