Component

PWM controllercurrent modeSOP8UC3843power supply controller

UC3843D8TR-TUDI is an 8-pin SOP8 current-mode PWM controller with 8.4 V UVLO turn-on, a 5 V reference, and a high-current output stage.

Best for

  • offline PWM power supplies
  • DC-DC converters
  • current-mode MOSFET control

Avoid if

  • the design requires an integrated high-side driver
  • verified lifecycle or compliance data is mandatory but unavailable

Check before use

  • VCC operating range and UVLO hysteresis
  • RT/CT oscillator settings
  • current-sense filtering and peak-current limit
  • output-driver loading and thermal dissipation
