The AW9968 is a white LED driver with integrated boost converter. The boost converter runs at 1.1MHz fixed switching frequency, with an internal 40V, 3A switch FET, the AW9968 can drive one string (up to 10 LEDs) and parallel LED strings. And it is quite applicable for smart phone as a flash mode light source, it can drive up to 3 times of full scale backlight current for 350ms when Strobe interface is high. The full-scale WLED current can be set by the equation 200mV/RSET in backlight mode. RSET should be changed for parallel applications. AW9968 integrates built-in soft-start function to minimize the power supply inrush current. AW9968 also integrates over-current protection , LED open protection and over temperature protection(OTP) to prevent chip from entering abnormal operating conditions.
