STMicroelectronics EVLSTNRG011-150 Power Supply Demonstration Board
STMicroelectronics EVLSTNRG011-150 Power Supply Demonstration Board is a 12V, 150W board for 90VAC to 264VAC mains. The EVLSTNRG011-150 has 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.
