LC5560LD Series
Single-Stage Power Factor Corrected Off-Line Switching Regulator ICs
Features and Benefits
• Integrated on-time control circuit (it realizes high power factor by average current control)
• Integrated startup circuit (no external startup circuit necessary)
• Integrated soft-start circuit (reduces power stress during start-up on the incorporated power MOSFET and output rectifier)
• Integrated bias assist circuit (improves startup performance, suppresses VCC voltage droop during operation, and allows use of low-rated ceramic capacitor on VCC pin)
• Integrated Leading Edge Blanking (LEB) circuit • Integrated maximum on-time limit circuit • Protection features:
▫ Overcurrent protection (OCP): pulse-by-pulse ▫ Overvoltage protection (OVP): latched shutdown ▫ Overload protection
