TNY253PN Frequently Asked Questions (FAQs)

  • The TNY253PN is a 25-watt offline switcher IC, so it can handle up to 25 watts of output power.
  • The TNY253PN has a thermal shutdown feature that turns off the IC if the junction temperature exceeds 150°C. Ensure good thermal design and heat sinking to keep the IC within a stable temperature range.
  • The recommended input voltage range for the TNY253PN is 85-265 VAC, which allows it to operate from a universal AC input.
  • Optimize the transformer design by selecting the correct turns ratio, ensuring the transformer is designed for the specific output voltage and current requirements, and following the guidelines in the TNY253PN datasheet.
  • The BYPASS pin is used to connect an external bypass capacitor to improve the power supply's noise immunity and reduce electromagnetic interference (EMI).
