3 Description

The DLPC6422 is a digital light controller for

the DLP® imaging chipset. The chipset comprises

the DLPC6422 light controller, the DLP digital

micromirror device (DMD) DLP78TUV, the DLPA100

power management device, and the DLPA300 DMD

micromirror driver (refer to the DMD data sheet).

This system is a great fit for DLP 3D Print and

other imaging applications that require high speed,

high resolution, UV wavelength, high light throughput,

and a robust system. For reliable operation, the

DLPC6422 light controller must always be used with

a DLP DMD DLP78TUV and respective DLP power

management devices.
