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

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 protection circuit used in these 230 VAC designs roughly measures the VAK across CCR1
