MAX1513EVKIT

Evaluation Kit for the MAX1513, MAX1514


Please check latest availability status for a specific part variant.

Description

The MAX1513 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that provides voltages and features required for active-matrix, thinfilm transistor (TFT), liquid-crystal displays. The EV kit contains a step-up switching regulator for TFT source driver supply, a positive two-stage charge pump and linear postregulator for the TFT gate-on (GON) supply, a negative one-stage charge pump and linear postregulator for the TFT gate-off (GOFF) supply, a gamma reference, and a low-voltage logic supply.

The EV kit operates from a DC supply voltage of +2.7V to +5.5V. The step-up switching regulator is configured for a +15V output at 500mA from a +4.5V to +5.5V input voltage. The positive charge pump and postregulator are configured for a +25V output using a single-stage charge pump providing 25mA. The negative charge pump and postregulator are configured for a -10V output using a single charge-pump stage providing 50mA. The gamma reference is configured for +14.7V providing 50mA. The low-voltage logic linear regulator is configured for +3.3V providing 500mA.

The MAX1513 EV kit demonstrates low-quiescent current and high efficiency (90%), and features overload protection for the input and all outputs. Up to 1.5MHz operation allows the use of tiny surface-mount components and results in a circuit height less than 1.8mm.

The MAX1513 EV kit can be also used to evaluate the MAX1514, which is a MAX1513 without a gamma linear regulator controller and a buffer amplifier.
