DESCRIPTION
Dynamic power feedback controls the external power supply to guarantee best efficiency. Built-in safety features include thermal shutdown as well as open and short LED detection. The device is programmable via serial interface. 2FEATURES
●● All LED backlight topologies xx No limit of VLED or ILED, device is not exposed to high voltage/high current●● Synchronization with TV frame xx VSYNC and HSYNC inputs available as well as a digital PLL integrated(2)
●● Optimum power savings through local dimming xx 16 fully flexible 12 bit PWM generators (period, high time, delay, reverse)
●● Lowest BOM xx Due to 2 pin concept of the output channel: no HV protection, no cascade FETs
●● Highest brightness uniformity xx One global high accuracy 10 bit DAC which sets the LED current (±0.5% accuracy)
●● Digital enhan
