Offline Switchers

PWM controlleroffline flybackcurrent modeSOP-8DIP-8

U2269 is an 8-pin current-mode PWM controller for offline flyback power supplies. It drives an external MOSFET and supports programmable frequency, burst mode and multiple protections.

Best for

  • Offline flyback adapters
  • Battery chargers
  • Low-standby-power SMPS designs

Avoid if

  • An integrated power switch is required
  • A verified compliance or lifecycle declaration is mandatory

Check before use

  • Package variant
  • VDD auxiliary-winding voltage
  • MOSFET gate-drive requirements
  • Current-sense resistor and OCP compensation
