UTC3842PWM controllercurrent modeSMPSDIP-8SOP-8

UTC3842-TD is an 8-pin current-mode PWM controller for offline and DC-DC switch-mode power supplies. It integrates UVLO, a 5 V reference, an adjustable oscillator, current sensing and a MOSFET driver.

Best for

  • Offline flyback power supplies
  • Current-mode DC-DC converters
  • MOSFET-driven switch-mode converters

Avoid if

  • Applications requiring an ambient range beyond 0 °C to 70 °C without further qualification
  • Designs requiring a controller package other than DIP-8 or SOP-8

Check before use

  • Confirm actual package ordering option
  • Validate startup and hold-up VCC supply
  • Set RT/CT timing for the intended switching frequency
  • Verify current-sense scaling and protection response
