STMicroelectronics 12V – 150W Power Supply Power Module for STNRG011 for Computer

The EVLSTNRG011-150 is a 12 V, 150 W power supply demonstration board for 90 V ac to 264 Vac mains, which is representative of an AC/DC converter for an all in one (AIO) computer or general purpose high power adapter. The design is based on the STNRG011 IC, digital combo that controls a two-stage AC/DCSMPL. The front-end is a transition mode PFCpre-regulator and the second stage is an LLC Resonant converter. The SRK2001 implements the synchronous rectification in order to obtain higher efficiency.
