ماسفت درایور NCP1631

General Features :

  • Near−Unity Power Factor
  • Substantial 180° Phase Shift in All Conditions Including Transient Phases
  • Frequency Clamped Critical Conduction Mode (FCCrM) i.e., Fixed Frequency, Discontinuous Conduction Mode Operation with Critical Conduction Achievable in Most Stressful Conditions
  • FCCrM Operation Optimizes the PFC Stage Efficiency Over the Load Range
  • Out−of−phase Control for Low EMI and a Reduced rms Current in the Bulk Capacitor
  • Frequency Fold−back at Low Power to Further Improve the Light Load Efficiency
  • Accurate Zero Current Detection by Auxiliary Winding for Valley Turn On
  • Fast Line / Load Transient Compensation
  • High Drive Capability: −500 mA / +800 mA
  • Signal to Indicate that the PFC is Ready for Operation (“pfcOK”Pin)
  • VCC Range: from 10 V to 20 V
