MAX17010EVKIT

Product Details

The MAX17010 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed circuit board (PCB) that provides the voltages and features required for active-matrix, thin-film transistor (TFT), liquid-crystal displays (LCDs). The EV kit contains a step-up switching regulator, a high-speed operational amplifier (op amp), and eight high-voltage level-shifting buffers for scan-driver applications.

The EV kit operates from a DC supply voltage of 1.8V to 5.5V. The step-up switching regulator is configured for a 8.5V output providing at least 300mA from a 2.7V input. The positive charge pump is configured for a 23V output providing at least 20mA. The negative charge pump is configured for a -7.5V output providing at least 20mA. The op amp is configured for 4.25V, capable of providing up to ±150mA peak. The high-voltage, level-shifting scan driver buffers eight logic inputs and shifts them to a desired level to drive TFT-LCD row logic.

The MAX17010 EV kit demonstrates low quiescent current and high efficiency (> 85%) for maximum battery life. Operation at 1.2MHz allows the use of tiny surface-mount components. The MAX17010 thin QFN package (0.8mm maximum height), with low-profile external components, allows this circuit to be less than 1.2mm high.
