3 Description

The DLPC8445, DLPC8445V, and DLPC8455 are 4K

UHD digital display controllers for TI DLP® Products.

The DLP chipset comprises one display controller,

one matched DMD, the DLPA3085 or DLPA3082

power management IC, and the DLPA100 motor

driver IC (for laser-phosphor illumination systems

only). This chipset fits display systems that require

high resolution and high brightness in a small

form factor. For reliable operation, the DLPC8445,

DLPC8445V, or DLPC8455 display controller must

always be used with the correct DMD and the

DLPA3085 or DLPA3082 PMIC. Note: DLPA3085 is

not supported by the DLPC8455.
