The EVL011A150ADP is a 12 V, 150 W power supply demonstration board for 90 Vac to 264 Vac 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 STNRG011A 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.

No auxiliary supply is needed due to the very low consumption at no-load.

A full set of auxiliary functions and protections is also provided; this allows to reduce the overall BOM while maintaining a rugged design.

The performance of the EVL011A150ADP 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.
