TinySwitch-LToffline switcherflyback650 V MOSFETPDIP-8CON/OFF control

TNY177PN is a TinySwitch-LT offline flyback controller with an integrated 650 V MOSFET in a PDIP-8C package. It uses ON/OFF regulation and offers selectable current-limit modes through the BP/M capacitor.

Best for

  • Low-power isolated flyback supplies
  • Auxiliary and standby power rails
  • Through-hole power-supply designs

Avoid if

  • A confirmed surface-mount package is required
  • Compliance or lifecycle documentation is mandatory but unavailable
  • The application requires power beyond the validated thermal and transformer design range

Check before use

  • Confirm TNY177PN suffix, package, and lead finish
  • Use a primary clamp and verify drain voltage remains below 650 V
  • Check transformer saturation and leading-edge current spikes
  • Verify thermal margin at low-line maximum output power
