Description

AW99706 is a highly accurate, highly matching six-string LCD backlighting power solution for notebook. It is a highly integrated step-up DC-DC converter operating with a wide input voltage for 2.7V to 24V and a temperature range from -40°C to 85°C. AW99706 integrates a high voltage MOSFET and six high accuracy, high voltage current sinks. Each current sink can be regulated up to 50mA. The LED current can be adjusted via an I2C interface and/or through a PWM signal. The PWM dimming resolution is up to 12-bit. AW99706 supports 300kHz to 1.7MHz switching frequency. Flexible selection of switching frequency according to efficiency and component size. AW99706 provides 3 ramp control modes for smooth transform of backlight brightness. Soft start mode can only be chose during the process of turning on and off backlight. Fade in/out mode and slope mode can be chose during both turning on/off backlight and dimming transition. Thorough protection features include over voltage limit, over temperature, over current protection, input undervoltage lockout, LED open and short detection. The protection status will be showed in register.
