TNY280PG datasheet by Power Integrations

TNY280PG Frequently Asked Questions (FAQs)

• What is the maximum output power that the TNY280PG can handle?
  The TNY280PG is a 8-pin, offline switcher IC that can handle up to 8W of output power.
• How do I ensure the TNY280PG operates within a specific temperature range?
  The TNY280PG has a built-in thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. Ensure proper heat sinking and thermal design to keep the device within the recommended operating temperature range of -40°C to 125°C.
• What is the recommended input voltage range for the TNY280PG?
  The recommended input voltage range for the TNY280PG is 85-265VAC, with a maximum input voltage of 300VAC.
• How do I optimize the design for EMI compliance?
  To optimize the design for EMI compliance, ensure proper PCB layout, use a common-mode choke, and add EMI filters as needed. Follow the layout guidelines provided in the datasheet and application notes.
• What is the purpose of the BYPASS pin on the TNY280PG?
  The BYPASS pin is used to connect an external capacitor to bypass the internal voltage regulator, allowing the device to operate from an external voltage source.
