EVL012LED

EVL012LED is an LED driver board. This architecture is based on a two-stage approach: a front-end PFC preregulator and a downstream resonant half-bridge converter, using the new STNRG012 IC that embeds the controllers of both sections in the same device. Thanks to the STNRG012, the main features of this design are high efficiency, low power consumption at no load without an auxiliary supply, good power factor with low harmonic content, and reduced part count. The board also has a full set of protection features including output overload, short-circuit, and overvoltage, all of which can be easily defined as latched or auto-restart, simply changing a value in the non-volatile memory of the controller.
