Component

current-mode PWMUC3844ASOP8offline powerDC/DC control

UC3844AD8TR-TUDI is a fixed-frequency, current-mode PWM controller for offline and DC/DC power converters, supplied in an 8-pin SOP package.

Best for

  • Offline PWM power supplies
  • DC/DC converters
  • Power MOSFET gate-drive control

Avoid if

  • The design requires a duty cycle above the UC3844 family limit of approximately 50%.

Check before use

  • UVLO thresholds and startup supply behavior
  • Current-sense filtering and peak-current limit
  • Compensation network and SOP8 footprint
