White LED Diver for Backlight of Medium/Large-sized LCDs - BD9271KUT
BD9271KUT is a white LED diver used on backlight of Medium/Large-sized LCDs. This IC can achieve dimming function by SPI control. And through the SPI correspondence, it can set the ON/OFF of each switch, analog dimming and etc. The signals of PWM dimming can set the frequency, ON time and delay of PWM by inputting the external signals to the register. BD9271KUT has equipped several protection functions to deal with the abnormal states, including LED OPEN protection, LED SHORT protection, external current setting resistance SHORT protection, external MOS transistor SHORT protection, etc. So it can be used in a wide output voltage range and various load conditions.
