UC2844D8TR-TUDI

Component

PWM controllercurrent modeSOP8power conversion

The UC2844D8TR-TUDI is an SOP8 fixed-frequency current-mode PWM controller for power-converter switching control, with an integrated error amplifier, current-sense comparator, UVLO, oscillator, and totem-pole output.

Best for

  • Fixed-frequency offline power converters
  • DC-to-DC converter control
  • Driving a power MOSFET

Avoid if

  • The design requires more than 50% maximum duty cycle
  • Verified lifecycle or compliance documentation is mandatory but unavailable

Check before use

  • Supply-voltage operating range and UVLO hysteresis
  • Timing resistor and capacitor values
  • Current-sense filtering and peak-current limit
  • Output-stage load and thermal conditions
