Question: How to design the LT3752-1 forward converter with secondary diode rectification and TL431 shunt regulator with optocoupler Feedback?
Answer: Instead of using a secondary synchronous rectifier controller, designer can opt to choose diode rectification with shunt regulator and optocoupler for the feedback network. Below documentation will provide some guidance for the connection and design.
- General documentation that may be helpful for the design application found in page 2: .ds21-power_ your-isolated-system-effortlessly.pdf (analog.com).
- Contains design guidelines for an Active Clamp forward controller with Optocoupler Feedback found in page 19: Microsoft Word - AN5780.docx (analog.com).
