Beschreibung
The NCP1680 Evaluation Board (EVB) user guide demonstrates a universal line, 300 W totem pole PFC built using NCP1680. NCP1680 is intended for Industrial power supplies, Telecom/5G/Networking power, USB PD, Gaming consoles, UHD TV power supplies, and Lighting applications. TPFC topology eliminates the need for heatsinks or forced air in the NCP1680 EVB while operating at an ambient of 25°C.
Eigenschaften
- Totem Pole PFC Topology Eliminates Input Diode Bridge Enabling Very 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 under Light 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 Effect Sensors
- Soft Skip Mode with a Skip Flag for Optimizing Light LoadPerformance
- Near Unity Power Factor in All Operating Modes
- PFCOK Indicator
