DN05063/D, 2-Stage Parallel-to-Series, ENERGY STAR Low-Cost Linear LED Driver Design (120 VAC)

DN05063/D, LED Driver Design uses innovative techniques to provide a cost-efficient and effective AC LED lighting solution for 120 VAC mains power. Its primary features are high efficiency, high power factor, low THD, dimming capability, scalable nature, and ENERGY STAR compliant efficacy. The circuit is designed for use with input voltages between 110 VAC and 130 VAC. The driver uses a parallel-to-series topology that dynamically adjusts the total LED forward voltage (Vf) to match the bridge output voltage. This practice helps the circuit obtain its high efficiency
