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.
