FAN104W
Overview
This highly integrated PWM controller, FAN104W, provides several features to enhance the performance of low-power flyback converters. The proprietary topology of FAN104W enables simplified circuit design for battery charger applications.
- Achieves <30 mW; Energy Star’s 5-Star Level
- Proprietary 500 V High-Voltage JFET Startup Reduces Startup Resistor Loss
- Low Operation Current in Burst Mode: 600 µA
- Constant-Voltage (CV) and Constant-Current (CC) Control without Secondary-Feedback Circuitry
- Green Mode: PWM Frequency Linearly-Decreasing
- PWM Frequency at 85 kHz with Frequency Hopping to Solve EMI Problem
- Boundary-Conduction-Mode (BCM) Operation at Lower AC Input Voltage
- Cable Compensation in CV Mode
- Cycle-by-Cycle Current Limiting
- Gate Output Maximum Voltage Clamped at 14 V
