Product Details

The MAX17103 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB that provides the voltages and features required for active-matrix, thin-film transistor (TFT), liquid-crystal display (LCD) applications. The EV kit contains a high-performance step-up regulator, a 350mA low-dropout linear regulator, a high-speed operational amplifier (op amp), a positive charge pump for the TFT gate-on supply, a negative charge pump with a negative linear regulator controller for the TFT gate-off supply, and a high-voltage, level-shifting scan driver.

The EV kit operates from a DC supply voltage of +2.3V to +5.5V. The step-up switching regulator is configured for a +8.5V output providing at least 250mA from a +2.7V input. The positive charge pump is configured to provide a +23V output providing at least 20mA. The negative charge pump with negative linear controller is configured to provide a -6V output providing at least 20mA. The op amp is configured for +4.25V and has a ±200mA (typ) output short-circuit current. The high-voltage, level-shifting scan driver buffers three logic inputs and shifts them to a desired level to drive TFT-LCD row logic.
