ماسفت درایور NCP1631
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
