DC DC Switching Controllers

active clampPWM controllercurrent modeforward converterflyback converterSOIC-16

UCC2893DR is a SOIC-16 current-mode active-clamp PWM controller intended for forward or flyback power converters using an N-channel auxiliary clamp switch.

Best for

  • Active-clamp forward converters
  • Active-clamp flyback converters
  • 48 V isolated DC/DC power stages

Avoid if

  • A P-channel auxiliary clamp driver is required
  • The input startup rail exceeds the 110 V VIN rating

Check before use

  • N-channel AUX clamp gate-drive implementation
  • Current-sense resistor and slope-compensation network
  • VDD bypass and bootstrap-bias hold-up capacity
