MAX17113 Evaluation Kit

Evaluates: MAX17113

General Description

The MAX17113 evaluation kit (EV kit) is a fully assem-

bled and tested surface-mount PCB that provides the

voltages and features required for thin-film transistor

(TFT) liquid-crystal display (LCD) TV panels. The EV

kit includes a step-down switching regulator, a step-up

switching regulator, a positive two-stage charge pump

for the TFT gate-on supply, and a negative single-stage

charge pump for the TFT gate-off supply.

The MAX17113 EV kit operates from a DC supply volt-

age of +10.8V to +13.2V, as configured. The step-down

switching regulator is configured for a +3.3V output

providing at least 2A. The step-up switching regulator is

configured for a +16V output providing at least 1.5A. The

positive charge pump is configured for a +35V output

providing at least 100mA. The negative charge pump

is configured for a -6V output providing at least 100mA.

Evaluates: MAX17113 MAX17113 Evaluation Kit Step-Up Regulator Output-Voltage Selection (AVDD) The output voltage (VIN to 18V) of the main step-up regulator is set by connecting a resistive voltage-divider from the output (AVDD) to AGND with the center tap connected to FB1. Calculate R3 with the following equation: resistors. For VGOFF less than -16V, select C15 with a higher voltage rating.

MAX17113 Evaluation Kit VGON Discharge Path The MAX17113 EV kit features a method to configure the VGON discharge path using resistor R15 and jumper JU6. When CTL is low, GON is connected to DRN, allowing VGON to discharge through resistor R15. JU6 selects the discharge path by connecting R15 to AVDD (through diode D6) or to PGND. Table 6 lists the selectable JU6 jumper options.
