Description
The NCP1680 Evaluation Board (EVB) user guidedemonstrates a universal line, 300 W totem pole PFC builtusing NCP1680. NCP1680 is intended for Industrial powersupplies, Telecom/5G/Networking power, USB PD,Gaming consoles, UHD TV power supplies, and Lightingapplications. TPFC topology eliminates the need forheatsinks or forced air in the NCP1680 EVB while operatingat an ambient of 25°C.
Features
- Totem Pole PFC Topology Eliminates Input Diode Bridge EnablingVery High Efficiency & Compact Design
- AC Line Monitoring Circuit & AC Phase Detection
- Brownout Detection
- Critical Conduction Mode (CrM) Operation
- Discontinuous Conduction Mode (DCM) with Valley Turn On underLight Load Conditions
- Frequency Foldback in DCM with 25 kHz Minimum Frequency
- Digital Loop Compensation
- Simplified Valley Sensing
- Novel Current Limit Scheme Eliminates the Needs for Hall EffectSensors
- Soft Skip Mode with a Skip Flag for Optimizing Light LoadPerformance
- Near Unity Power Factor in All Operating Modes
- PFCOK Indicator
Typical applications
