Connect the +3.3V DC power supply to the VDD and
AGND PCB pads.
Connect the +35V DC power supply to the VON and
AGND PCB pads.
Connect the -25V DC power supply to the VOFF and
AGND PCB pads.
Turn on the power supply.
Note that the logic inputs (STV, CPV1, and CPV2)
must be set to AGND or VDD.

The MAX17121 EV kit contains all the components nec-
essary to evaluate the MAX17121 IC. The MAX17121 is a
dual, high-voltage, level-shifting scan driver to drive TFT
panel integrated gate logic. The drivers’ outputs swing
from -30V to +40V and two sets of complementary out-
puts are provided to allow charge sharing during state
changes. The EV kit operates from a DC supply range
from +2.2V to +3.6V and consumes 250FA (typ).
The MAX17121 EV kit provides PCB pads to connect the
logic inputs and scan-driver outputs. Test points are also
provided to monitor the charge sharing, EN, and DISH
states. Jumper JU1 is provided to enable/disable the
MAX17121 device (see Table 1).
