FAN6754WA Overview
Description
The highly integrated FAN6754WA PWM controller provides several features to enhance the performance of flyback converters. To minimize standby power consumption, a proprietary Green-Mode function provides off-time modulation to continuously decrease the switching frequency under light-load conditions.
Key Features
- High-Voltage Startup
- AC Input Brownout Protection with Hysteresis
- Monitor HV to Adjust VLimit
- Low Operating Current: 1.5 mA
- Linearly Decreasing PWM Frequency to 22 kHz
- Frequency Hopping to Reduce EMI Emission
- Fixed PWM Frequency: 65 kHz
- Peak-Current-Mode Control
- Cycle-by-Cycle Current Limiting
- Leading-Edge Blanking (LEB)
