Power Integrations provides a recommended PCB layout in their application notes (e.g., AN-63) and evaluation board designs. It's essential to follow these guidelines to ensure good thermal performance and minimize thermal resistance.
Power Integrations provides a transformer selection guide in their application notes (e.g., AN-41) and online tools. Factors to consider include input voltage, output voltage, power rating, and physical size constraints.
To minimize EMI, it's essential to follow good layout practices, such as keeping the input and output stages separate, using a common-mode choke, and placing the EMI filter components close to the INN3879C-H801-TL. Power Integrations provides guidance on EMI filter design in their application notes (e.g., AN-64).
To ensure reliable start-up and shutdown, it's essential to follow the recommended soft-start and shutdown procedures outlined in the datasheet and application notes. This includes using a soft-start circuit and a shutdown pin capacitor to prevent voltage spikes.
The INN3879C-H801-TL has built-in thermal monitoring and protection features, including overtemperature protection (OTP) and thermal shutdown. These features help prevent damage to the device in case of overheating or excessive temperature rise.
