FAN103W
Overview
This third-generation Primary-Side-Regulation (PSR) and highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. The proprietary topology, TRUECURRENT®, of FAN103W enables precise CC regulation and simplified circuit for battery charger applications.
- Low Standby Power Under 30mW
- High Voltage Startup
- Fewest External Component Counts
- Constant-Voltage (CV) and Constant-Current (CC) Control without Secondary-Feedback Circuitry
- Green-Mode Function: Linearly-Decreasing PWM Frequency
- Fixed PWM Frequency at 50kHz with Frequency Hopping to Solve EMI Problem
- Cable Compensation in CV Mode
- Peak-Current-Mode Control in CV Mode
- Cycle-by-Cycle Current Limiting
- VDD Over-Voltage Protection with Auto Restart
