Constant current source for interior LED lighting

Highly efficient and compact, LEDs have become the de-facto choice for interior lighting applications, from cluster backlighting to mood lighting. However, LEDs are sensitive to operating current so, for any single or string system, a constant steady state current is vital. That’s why constant current source devices make the ideal solution for driving LEDs in the electrically noisy environment of vehicles. Our space-saving NCR series complements the efficiency of LEDs perfectly with accurate and stable outputs.
