Component

PWM controllercurrent modeSOP8offline powerDC-to-DC

UC2845D8TR-TUDI is a SOP8 fixed-frequency current-mode PWM controller intended for offline and DC-to-DC converter control.

Best for

  • offline PWM power supplies
  • DC-to-DC converters
  • power MOSFET gate-drive control

Avoid if

  • the design requires more than 50% duty cycle from a single controller output
  • the supply can exceed the 30 V absolute maximum

Check before use

  • SOP8 footprint and 1.27 mm pin pitch
  • UVLO behavior across the supply ramp
  • current-sense filtering and peak-current limit
  • gate-drive current and switching losses
