DESCRIPTION
The EV3414-J-00A is a Boost converter
evaluation board for the MP3414, a
synchronous, 1MHz fixed frequency, current
mode step-up converter with output to input
disconnect. The device can step up single-cell
and two-cell alkaline, NiCd, and NiMH batteries
up to 4V.
It can startup from an input voltage as low as
0.8V and provides inrush current limiting as well
as output short circuit protection.
The output voltage also can be regulated when

, and the P-channel MOS is no longer
act as a low impedance switch.
The EV3414-J-00A regulates the output voltage
up to 3.3V from single cell AA battery without
the uses of an external Schottky diode.
The MP3414 is offered in a TSOT23-8 package.
