EVLSTNRG011-150

12V, 150W power supply demonstration board for 90VAC to 264VAC mains which is representative of an AC/DC converter for an all in one (AIO) computer or a general purpose high power adapter. The design is based on the STNRG011 IC, a digital combo that controls a two-stage AC/DC SMPL. The front-end is a transition mode PFC pre-regulator and the second stage is an LLC HB resonant converter. The SRK2001 implements the synchronous rectification in order to obtain higher efficiency. A full set of auxiliary functions and protection is also provided, this allows reduction of the overall BOM while maintaining a rugged design. The performances of the EVLSTNRG011-150 can meet the requirements of major standards ENERGY STAR® for computers ver. 6.1, EuP Lot 6 Tier 2, European CoC ver. 5 Tier-2, in terms of efficiency, no-load input power and power factor and feature harmonics content well below the limits of European Standard EN61000-3-2 Class D and Japanese standard JEITA-MITI Class-D regulations.
