  • The NCL2801 is a current mode CRM Boost PFC control IC which can provide the best class THD performance over extended operating range utilizing ON Semiconductor’s THD enhancer technique. Efficiency and standby power are enhanced with Valley Count Frequency Fold-back (VCFF) method.
  • Features
  • Valley Count Frequency Foldback - Maximize efficiency over wide load range
  • Dynamic Response Enhancer - Lower output undershoot
  • Soft/Fast OVP - Lower output overshoot
  • THD Enhancer - Improve THD performance
  • Line level feed-forward - Optimal loop gain in universal input
  • Protections - Brown Out - Thermal Shutdown - OVP - Over Current limitation - Pin open/short protection - High System Reliability
  • Wide Vcc (10.5~28 V) range/ 3 Vcc startup level - Design Flexibility
  • OTA Error Amp - Easy loop design and lower power loss by higher RFB
  • Applications
  • All Off Line Appliances Requiring Power Factor Correction
  • End Products
