CCRACGEVB An AC LED Lighting Evaluation Board Using Constant Current Regulators (CCR) Evaluation Board User's Manual
■Engineers developing solid-state lighting control systems need to balance circuit efficiency, power factor (PF), total harmonic distortion (THD), total cost of bill of materials (BOM) and input voltage range to cover large geographic regions and aesthetics to satisfy different customer requirements. The CCRACGEVB allows engineers to evaluate six different topologies as they approach this difficult balancing act.
■The CCRACGEVB (see Figure 1) has an input voltage range of 12 VAC to 250 VAC and showcases the NSIC20x0JBT3G series of 120V CCRs and the NSI50150ADT4G (150 – 350 mA Adjustable) CCR. It has circuit topologies for “Straight LED Driving”, “Capacitive Drop LED Driving” and “Chopper LED Driving”, all with and without dimming by typical triac dimmers. It has a simple current inrush limiting circuit to suppress the impact of initial high inrush currents and power spikes.
