TNY264G datasheet by Power Integrations

TNY264G Frequently Asked Questions (FAQs)

• What is the maximum output power of TNY264G?
  The maximum output power of TNY264G is dependent on the input voltage, output voltage, and ambient temperature. However, as a general guideline, it can deliver up to 12W of output power with a 230VAC input and 5V output.
• How do I ensure the reliability of the TNY264G in my design?
  To ensure reliability, follow the recommended layout guidelines, use a suitable heat sink, and ensure that the component is operated within its specified temperature range. Additionally, consider using a fuse or overcurrent protection to prevent damage from excessive current.
• What is the purpose of the BYPASS pin on the TNY264G?
  The BYPASS pin is used to connect an external capacitor to the internal voltage regulator. This helps to improve the power supply rejection ratio (PSRR) and reduce the output voltage ripple.
• Can I use the TNY264G in a design with a high-temperature environment?
  The TNY264G has a maximum operating temperature of 150°C. If your design requires operation above this temperature, you may need to consider a different component or implement additional cooling measures.
• How do I calculate the output voltage of the TNY264G?
  The output voltage of the TNY264G is determined by the input voltage, the turns ratio of the transformer, and the output voltage setting resistor (RSET). The datasheet provides a formula to calculate the output voltage based on these parameters.
