TNY278PN Frequently Asked Questions (FAQs)

  • The TNY278PN is a 8-pin offline switcher IC that can handle up to 8W of output power.
  • The TNY278PN has a built-in thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. Ensure good thermal design and heat sinking to keep the device within a safe operating temperature range.
  • The recommended input voltage range for the TNY278PN is 85-265VAC, which makes it suitable for universal input applications.
  • Optimize the transformer design by following the guidelines in the application note AN-58 from Power Integrations, which provides detailed information on transformer design and selection for the TNY278PN.
  • The BYPASS pin is used to connect an external bypass capacitor to the internal voltage regulator, which helps to reduce noise and improve the overall power supply performance.
