FAN6863
Overview
A highly integrated PWM controller, FAN6863 provides several features to enhance the performance of flyback converters. To minimize standby power consumption, a proprietary Green Mode provides off-time modulation to continuously decrease the switching frequency under light-load conditions.
- Low Standby Power: Under 0.1W
- Low Startup Current: 8µA
- Low Operating Current at Green Mode: 600µA
- Peak-Current Mode Operation with Cycle-by-Cycle Current Limiting
- PWM Frequency Continuously Decreasing with Burst Mode at Light Loads
- VDD Over-Voltage Protection (OVP)
- Constant Output Power Limit (Full AC Input Range)
- Internal Latch Circuit (FAN6863L) for OVP, OTP
- SENSE Pin Short-Circuit Protection (SSCP)
- Fixed PWM Frequency (65KHz) with Frequency Hopping
