MAX17120 Evaluation Kit

General Description

Features

S Three High-Voltage, Level-Shifting Scan Drivers

S +2.2V to +3.6V Input Supply Voltage Range (VDD)

S -30V to +40V Output Swing

The MAX17120 evaluation kit (EV kit) is an assembled

and tested circuit board that contains all the components

necessary to evaluate the MAX17120 IC. The MAX17120

is a triple, high-voltage, level-shifting scan driver to drive

the TFT panel gate logic. The driver outputs swing from

-30V to +40V. To save power, three sets of complemen-

tary outputs 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 500FA (typ).

Procedure

The MAX17120 EV kit is fully assembled and test-

ed. Follow the steps below to verify board operation.

Caution: Do not turn on the power supply until all

connections are completed.

Note: H = VDD, L = GND, ↑ = rising edge, CS = charge-share

state, and X = don’t care.

Detailed Description of Hardware

The MAX17120 EV kit contains all the components nec-

essary to evaluate the MAX17120 IC. The MAX17120 is a

triple, high-voltage, level-shifting scan driver to drive TFT

panel gate logic. The drivers’ outputs swing from -30V

to +40V and three sets of complementary outputs 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 500FA (typ).

1) Connect the +3.3V DC power supply to the VDD and

AGND PCB pads.

2) Connect the +35V DC power supply to the VON and

AGND PCB pads.

3) Connect the -25V DC power supply to the VOFF and

AGND PCB pads.

4) Turn on the power supply.

The MAX17120 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

MAX17120 device (see Table 1).

5) Note that the logic inputs (STV, CPV1, CPV2, and

CPV3) must be set to AGND or VDD.

6) Verify the STVP logic at the respective test points:
