Single Stage 200W AC-DC LLC Series Resonant Conv for 120VAC & 230VAC Input Reference Design


Design files


The PMP10283 reference design provides 30V/100W and -30V/100W outputs from AC line voltage to a single LLC resonant converter stage. This design is featured with its low circuit cost and high efficiency (over 90% @ 120VAC full load and ~92% @ 240VAC full load). This design uses the UCC25600 resonant converter controller for LLC resonant converter.

  • 88VAC-132VAC or 176VAC-264VAC Input
  • +/-30V 200W output
  • Up to 92% converter efficiency
  • Single stage AC-DC LLC-SRC
  • Low circuit cost
