SG6849
Overview
This highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. To minimize standby power consumption, the proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency under light-load and zero-load conditions.
- Linearly Decreasing PWM Frequency
- Green-Mode Under Light-Load and Zero-Load Conditions
- Constant Voltage (CV) and Constant Current (CC)
- No Secondary Feedback
- Low Startup Current: 5μA
- Low Operating Current: 3.6mA
- Leading-Edge Blanking (LEB)
- Constant Power Limit
- Universal AC Input Range
- Synchronized Slope Compensation
