TOPSwitch-IIoffline PWM switch700 VPDIP-8NRND

TOP222PN is a PDIP-8 TOPSwitch-II offline PWM power-switch IC with an integrated 700 V MOSFET and typical 0.50 A current limit.

Best for

  • Existing low-power offline flyback designs
  • Standby power supplies using through-hole assembly

Avoid if

  • New product designs requiring an actively recommended component
  • Designs without verified transformer saturation and drain-clamp margins

Check before use

  • Check package thermal performance on the actual PCB copper area
  • Keep drain clamp voltage below the recommended 200 V clamp value
  • Verify peak flux density and drain-current rise during overload
