Product Overview

The UC3854N is a High Power Factor Preregulator that provides active power factor correction for power systems that otherwise would draw non-sinusoidal current from sinusoidal power lines. This device implements all the control functions necessary to build...
  • Control boost PWM to 0.99 power factor
  • Limit line current distortion to <5%
  • World-wide operation without switches
  • Feed-forward line regulation
  • Average current-mode control
  • Low noise sensitivity
  • Low start-up supply current
  • Fixed-frequency PWM drive
  • Low-offset analogue multiplier/divider
  • 1A Totem-pole gate driver
  • Precision voltage reference
  • Green product and no Sb/Br
