UCC28C55DR

Power Management (PMIC)

PWM controllercurrent-mode controlSOIC-8offline powerMOSFET gate drive

UCC28C55DR is an 8-pin SOIC BiCMOS current-mode PWM controller with integrated feedback, oscillator, current limiting, UVLO, and MOSFET gate drive.

Best for

  • Offline isolated power converters
  • Single-ended DC/DC converters using Si or SiC MOSFETs

Avoid if

  • The design requires a duty cycle near or above 50%
  • The controller supply can exceed the 30 V absolute maximum

Check before use

  • UVLO startup and shutdown behavior
  • Peak current-sense threshold and slope compensation
  • VDD and VREF bypassing
  • SOIC PCB footprint and high-current gate-drive routing
