The MAX17062 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed-circuit board (PCB) that provides the voltages required for active-matrix, thin-film transistor (TFT), liquid-crystal displays (LCDs). The EV kit contains a pulse-width-modulated (PWM) step-up switching regulator, a positive single-stage charge pump for the TFT gate-on supply, and a negative single-stage charge pump for the TFT gate-off supply.
The EV kit operates from a DC supply voltage of +4.5V to +5.5V and is configured to operate with a switching frequency of 1.2MHz. The step-up switching regulator is configured for a +15V output and can provide 600mA with a +4.5V input. The positive charge pump is configured for a +29V output providing 30mA. The negative charge pump is configured for a -15V output providing 30mA.
The MAX17062 EV kit features low-quiescent current and high-conversion efficiency (90%). The high switching frequency allows the use of small, surface-mount components.
