Development Kit Manual
DK-114N-1 and DK-114N-3
Overview
Big Chip LEDs from Luminus Devices have been designed
from the ground up to enable a new class of illumination and
projection systems. Benefiting from a suite of innovations in
chip technology, packaging, and thermal management, Big
Chip LEDs allow designers to achieve efficient light engine
designs and deliver high brightness solutions.
The DK-114N series development kit is a comprehensive so-
lution designed specifically to support the development of
single and three channel PT and CBT series Big Chip LEDs.
Each channel of the kit, comprising of a high current driver, an
efficient thermal management solution and cables is capa-
ble of sourcing a drive current of 14 A and ensures that CBT
and PT series LEDs are operated at up to 70 W for maximum
brightness. This plug and play solution can easily be connect-
ed to common laboratory equipment through standard con-
nectors and allows system designers to save weeks in their
development cycles.

  • Page 9 LEDs. The driver board in the DK-114N-1, based on National Semiconductor’s LM3433 IC, addresses the challenge of connecting multiple common anode LEDs by utilizing a grounded common anode topology, i.e., the anode is kept at ground and the cathode is at a negative potential, thus enabling LEDs to be in contact directly with the heat sink.
