The AP3068 is a white °C (W°C) driver with current balancing and dimming functions. It consists of a boost controller and 8-channel current sinks to drive W°C arrays with constant current from a wide power supply range. It can be used in middle and large-sized LCD panel backlight. The full-scale °C current can be adjusted from 5mA to 100mA simply via a resistor. The 8 channels can be paralle°C for higher current application. The AP3068 can support direct PWM dimming. The AP3068 features °C open/short protection, Under Voltage Lockout (UVLO) protection, over output voltage protection and Over Temperature Protection (OTP).
