The UCC38500DW is a BiCMOS PFC/PWM Combination Controller provides all of the control functions necessary for an active power-factor-corrected pre-regulator and a second-stage DC to DC converter. The controller achieves near-unity power factor by shaping t...
  • Combines PFC and downstream converter controls
  • Controls boost preregulator to near-unity power factor
  • Accurate power limiting
  • Improved feedforward line regulation
  • Peak current-mode control in second stage
  • Programmable oscillator
  • Leading-edge/trailing-edge modulation for reduced output ripple
  • Low start-up supply current
  • Synchronized second stage start-up, with programmable soft-start
  • Programmable second stage shutdown
  • Green product and no Sb/Br
