MAX1579EVKIT

Evaluation Kit for the MAX1579


Please check latest availability status for a specific part variant.

Description

The MAX1579 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX1578/ MAX1579. This MAX1579 EV kit drives six white LEDs in series for backlighting and includes complete bias supplies for small TFT displays. The internal charge pumps for the TFT bias supplies provide fixed +15V at 100µA for VON, -10V at 100µA for VOFF, and +5V at 25mA for the source driver. The MAX1579 EV kit can also evaluate the MAX1578. To evaluate the MAX1578, order a free sample along with this EV kit.
