Resonant LCC 90 W notebook power adapter based on the L6599 and STP9NK50ZF

This demonstration board is a 90 W wide-range mains AC-DC adapter which is power factor corrected. Its electrical specifications are suitable for typical high-end portable computer power adapters. The particular benefits of this design are the very low no-load input consumption (<0.5 W) and the very high global efficiency.

The architecture is based on a two-stage approach: a front-end PFC pre-regulator based on the L6563 TM PFC controller and a downstream multi-resonant half-bridge converter that makes use of the L6599 resonant controller.

Key Features

  • Latch mode: OVP acts while VOUT > 29 VDC
  • Hiccup mode: Auto recovery with SCP
  • Dimensions (L/W/H): 132 mm / 52 mm / 22 mm
  • High output power: 90 W (4.74 A, 19 VDC)
  • Universal AC mains range: 90 VAC to 264 VAC
  • Very low standby power: less than 0.5 W at 264 V
  • Efficiency > 88% at universal AC mains range
  • Very low output noise and ripple: less than 300 m VP-P
