Class 3 - Mulitple Output, High Efficiency Driven Flyback Converter for PoE Applications
View the Important Notice for TI Designs covering authorized use, intellectual property matters and disclaimers.
This converter is used for Class 3 PoE applications where high efficiency and multiple outputs are required. The flyback converter with synchronous rectifier provides excellent efficiency and small size for PoE applications such as IP Phones. The TPS23785B contains both the PoE Powered Device and the PWM controller functions.
- High efficiency (90%)
- Multiple outputs for 10V/0.2A, 5V/1A, 3.3V/1.5A
- Isolated Flyback with synchornous rectifier
- Small size solution
- Uses TPS23785 with PoE interface PD and PWM controller
- This circuit design is full-functional tested and recommended for new designs.
