STMicroelectronics EVL150W-HVSL Evaluation Board
STMicroelectronics EVL150W-HVSL Evaluation Board is an evaluation board of a 150W / 1A LED driver with wide input mains range. The electrical specifications are tailored on a typical high-power street lighting application. It is based on a two-stage architecture, consisting of a front-end PFC pre-regulator and a downstream half-bridge resonant tank converter. The pre-regulator is a transition mode PFC based on constant ON time control. The resonant converter is an LCC tank that is more suitable than an LLC tank to build a current source.
