DN05088/D, Dimmable, 9.5 W, 120 Vac CCR Lighting Circuit

DN05088/D, Design Circuit is an enhanced parallel-to-series LED lighting circuit. It uses updated control circuitry that allows the ability to accommodate multiple LED voltages by simply adjusting a single resistor (R3) as well as compensating for drift in LED voltage with temperature. It also has superb PF and THD performance, dimmability, low cost, and efficiency. The circuit is designed for input voltages between 100 VAC and 140 VAC . CCRs are used to provide constant LED current and to protect LEDs from over-voltage conditions. The circuit employs an additional CCR to increase LED current at high voltages for improved efficiency, PF and THD performance
