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.
