STMicroelectronics EVLCMB1-AIO210W Demonstration Board
STMicroelectronics EVLCMB1-AIO210W Demonstration Board is a 12V-210W converter for the typical specification of an AC/DC adapter. These include all-in-one systems with a wide input mains range, very low power consumption at light load, and good average efficiency. The architecture is based on a two-stage approach, a front-end transition mode PFC preregulator and a downstream LLC resonant half bridge converter. The PFC and LLC controllers are integrated in the STCMB1 combo IC. At a secondary site, synchronous rectification is implemented by means of the SRK2001.
