FL663
Overview
This third-generation Primary-Side-Regulation (PSR) and highly integrated PWM controller provides features to enhance the performance of LED illumination. The proprietary topology, TRUECURRENT®, enables precise CC regulation and simplified circuit for LED illumination applications.
- Low Standby Power: < 30 mW
- High-Voltage Startup
- Few External Component Counts
- Constant-Voltage (CV) and Constant-Current (CC) Control without Secondary-Feedback Circuitry
- Green-Mode: Linearly-Decreasing PWM Frequency with Cycle skipping.
- Fixed PWM Frequency at 50 kHz and 33 kHz with Proprietary Frequency Hopping to Solve EMI Problems
- Peak-Current-Mode Control in CV Mode
- Cycle-by-Cycle Current Limiting
- VDD Over-Voltage Protection (OVP)
- VDD Under-Voltage Lockout (UVLO)
