Digital LED driver ICs reduce flicker
6 October 2016 
The XDPL8220’s primary side control saves extra components, and also reduces cost and increases reliability, claims Infineon Technologies.
The two-stage architecture eliminates the low frequency variation from the mains supply and guarantees a stable output. The low stand-by power facilitates permanent operation of the electronic control gear, and standby power of less than 70mW reduces power consumption in the non-active mode.
Control algorithms make it possible to realise lighting for constant current or constant voltage mode in the same circuit. The driver provides a comprehensive set of parameters for adjusting the operating constraints, enabling it to be adapted to the target application.
Samples are available now, with production in January 2017.
