说明

AW99703 is a highly accurate, highly matching three-string LCD backlighting power solution. It is a highly integrated step-up DC-DC converter operating with a wide input voltage from 2.7V to 5.5V and a temperature range from -40°C to 85°C, accommodating 1-cell lithium ion battery or 5V supply. The AW99703 integrates a high voltage MOSFET, and three high accuracy, high voltage current sinks. Each current sink can be regulated up to 29.6mA in backlight mode. In flash mode, flash current sink can be regulated up to 79.9mA, and flash timeout can be regulated up to 1.5sec. The LED current is adjusted via an I2C interface or through a logic level PWM input. The PWM duty cycle is internally sensed and mapped to an 11-bit linear current. Thorough protection features include LED fault (open and short) protection, cycle-by-cycle current-limit protection, output over-voltage protection and thermal shutdown.
