Highly efficient, highly accurate and highly integrated to drive Mini-LEDs up to 8 x 72 areas with integrated MUX switch and current receiver. Flexible LED brightness control is possible with 12-bit LED current setting and 13-bit PWM high time setting.
The XP7576's extremely low MUX switching losses and current sink losses, as well as dynamic current sink voltage feedback control can greatly improve overall efficiency and thermal performance. The high level of integration helps to simplify the design.
Using a daisy-chained SPl interface for flexible control of the XP7576, the DPLL simplifies system requirements for PWM dimming control.The XP7576 offers flexible dimming modes, including PWM mode, DC mode or mixed mode dimming. Dedicated fault pins are used to indicate LED on, LED shorted, over-temperature and other status.
