Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The MAX1513 EV kit is fully assembled and tested.
Follow these steps to verify board operation. Do not turn
on the power supply until all connections are completed.

The MAX1513 EV kit contains a step-up switching regu-
lator, a positive two-stage charge pump with positive
high-voltage linear regulator, a negative one-stage
charge pump with negative high-voltage linear regula-

tor, a linear regulator for gamma reference, and a linear
regulator for low-voltage logic supply. The EV kit oper-
ates from a +4.5V to +5.5V DC power supply. The
switching frequency is 1.5MHz.
The step-up switching regulator (VMAIN) generates a
+15V output and can provide at least 500mA from
+4.5V to +5.5V. The TFT gate-on supply (GON) uses
one of the two positive charge-pump stages to gener-
ate +25V and can deliver 25mA. The TFT gate-off sup-
ply (GOFF) uses a charge-pump stage to generate
-10V and provides 50mA. The gamma reference
(VGAM) is set to +14.7V using a linear regulator and an
external pnp bipolar pass transistor and provides
50mA. The logic voltage supply (VLOG) is set to +3.3V
using a linear regulator and an external pnp bipolar
pass transistor and provides 500mA. All five outputs can
be adjusted (refer to the Output Voltage Selection
section in the MAX1513/MAX1514 IC data sheet).
The MAX1513 EV kit features a shutdown mode that
reduces the MAX1513 quiescent current to less than
150µA. The 2-pin jumper JU1 and 3-pin jumper JU5
control the shutdown mode and the frequency selection
for the MAX1513 EV kit.
jumpers’ options.
The positive charge pump of the MAX1513 EV kit fea-
tures an option to cascade up to two charge pumps’
stages. The first stage of the positive charge pump can
be connected to the source from PIN or VMAIN.
Jumpers JU2 and JU3 configure the number of stages
and select the voltage source for the positive charge
pump on the MAX1513 EV kit. Table 2 lists jumper JU2
