Texas Instruments DLPC8445/DLPC8445V Digital Display Controllers

Texas Instruments DLPC8445/DLPC8445V Digital Display Controllers are part of the TI DLP Products 4K UHD display chipsets. The chipset comprises the display controller (DLPC8445/DLPC8445V), the DLP472TP DMD, and the DLPA3085 or DLPA3082 power management integrated circuit. This solution fits display systems that require high resolution and high brightness in a small form factor. For reliable operation, the DLPC8445 or DLPC8445V display controller must always be used with the DLP472TP DMD and the DLPA3085 or DLPA3082 PMIC per application.
