The TNY290KG-TL can deliver up to 90W of output power, making it suitable for a wide range of applications, including LED lighting, battery charging, and power adapters.
To ensure the TNY290KG-TL operates within its SOA, follow the guidelines outlined in the datasheet, including keeping the junction temperature below 150°C, and ensuring the input voltage does not exceed 30V. Additionally, use a suitable heat sink and ensure good thermal management.
The BYPASS pin is used to connect a bypass capacitor to the internal voltage regulator, which helps to reduce noise and improve the overall stability of the device.
To optimize the design of the output filter, follow the guidelines outlined in the datasheet, including selecting the correct inductor value and type, and ensuring the output capacitor is suitable for the application. Additionally, use simulation tools or consult with a Power Integrations application engineer for specific guidance.
When designing the PCB layout for the TNY290KG-TL, ensure good thermal management by providing adequate heat sink area and thermal vias. Additionally, follow good layout practices, such as keeping high-frequency traces short and away from sensitive nodes, and using a solid ground plane to reduce EMI.
