U6116 is a 6-pin offline primary-side CV/CC controller for low-power flyback chargers and QR-buck constant-current LED drivers.

Best for

  • Low-power offline flyback chargers
  • Primary-side regulated AC/DC adapters
  • QR-buck constant-current LED drivers

Avoid if

  • Applications requiring an explicitly documented secondary-side feedback loop
  • Designs requiring stated automotive or safety qualification
  • Projects needing confirmed RoHS, REACH, MSL or lifecycle data

Check before use

  • SEL configuration for the intended topology
  • MOSFET current-sense resistor sizing
  • Transformer auxiliary and secondary turns ratios
  • VDD startup and clamp design
  • Thermal and fault testing of the completed converter
