GENERAL DESCRIPTION
The EV3209DJ-00A is the evaluation board for
the MP3209. The MP3209 is a current mode
step up converter intended for small, low power
applications. The MP3209 switches at 1.3MHz
and allows the use of tiny, low cost capacitors
and inductors 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.

QUICK START GUIDE
The output voltage of this board is set to 15V. The board layout accommodates most commonly used
inductors and output capacitors.
1. Preset Power Supply to 2.5V ≤VIN ≤6V.
2. Turn Power Supply off.
3. Connect Power Supply terminals to:
Positive (+): IN
Negative (–): GND
4. Connect Load to:
Positive (+): OUT
Negative (–): GND
5. Turn Power Supply on after making connections.
6. The MP3209 is enabled on the evaluation board once VIN is applied. To disable the MP3209,
short EN to GND.
7. The output voltage VOUT can be changed by varying R4. Calculate the new value using the
fomula:
