DN05079/D, 120 VAC & 230 VAC Direct-AC, Linear LED Driver Topology: CCR Straight Circuit (CCR-based LED Driver)

DN05079/D, Design Note presents a simple, low-cost LED driver topology useful for AC LED lighting solutions at any mains voltage or frequency. This cost-effective driver design combines good power factor, simplicity, high efficiency, and impressive driver scalability in a very adaptive and versatile platform solution. The circuit is designed for use within a wide input voltage range, and can be made to operate anywhere between 90 VAC and 300 VAC. The driver works best when optimized for a specific supply voltage range (such as 100 - 130 VAC or 190 - 250 VAC), which may influence LED load design
