STEVAL-ISC002V1 Resonant LCC 90 W notebook power adapter based on the L6599 and STP12NM50N Data Brief Features Dimensions (L/W/H): 132 mm / 52 mm / 22 mm Universal AC mains range: 90 VAC to 264 VAC High output power: 90 W (4.74 A, 19 VDC) Very low output noise and ripple: less than 300 m VP-P Very low standby power: less than 0.5 W at 264 V Hiccup mode: Auto recovery with SCP Latch mode: OVP acts while VOUT > 29 VDC Efficiency > 88% at universal AC mains range STEVAL-ISC002V1 Description 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.
