The maximum output power of the TNY380GN depends on the input voltage, output voltage, and the transformer turns ratio. However, as a general guideline, the TNY380GN can deliver up to 38W of output power with a suitable transformer design and proper thermal management.
To select the right transformer for the TNY380GN, you need to consider factors such as the input voltage, output voltage, output power, and the desired efficiency. Power Integrations provides a transformer design tool that can help you select the optimal transformer for your application.
The recommended PCB layout for the TNY380GN involves keeping the high-voltage nodes (e.g., Drain and Source) away from the low-voltage nodes (e.g., Vcc and GND) to minimize electromagnetic interference (EMI). Additionally, it's essential to provide a solid ground plane and to use a thermal relief pattern for the Drain pin to ensure good thermal performance.
To ensure the reliability and longevity of the TNY380GN, it's essential to follow proper design and manufacturing practices, such as using a suitable PCB material, ensuring proper soldering and assembly, and providing adequate thermal management. Additionally, you should also consider implementing overvoltage protection, overcurrent protection, and undervoltage lockout (UVLO) to prevent damage to the device.
No, the TNY380GN is designed for isolated topologies only. It's not suitable for non-isolated topologies due to its internal transformer and the requirement for electrical isolation between the input and output stages.
