Six Different Circuit Topologies Covering
Smallest Bill of Materials to Widest Input
Voltage: 12 VAC to 250 VAC.
Introduction
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.

range of 12 VAC to 250 VAC and showcases the
NSIC20xBT3G series of 120 V CCRs and the NSI50150
(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.
