UCC28C44DGKR

DC DC Switching Controllers

PWM controllercurrent-mode controlBiCMOSVSSOP-8power supply

UCC28C44DGKR is a low-power BiCMOS current-mode PWM controller for switching power supplies, with a 14.5-V/9-V UVLO profile and less-than-50% maximum duty cycle.

Best for

  • Offline switching power supplies
  • Isolated flyback or forward converters
  • General DC/DC power conversion

Avoid if

  • The design requires an output duty cycle above 50%
  • VDD transients cannot be limited below 20 V

Check before use

  • Confirm the VSSOP-8 footprint and 0.65-mm pin pitch
  • Select RT/CT values for the required oscillator frequency
  • Validate current-sense filtering and loop compensation
