Digital LED driver ICs have low standby power
Digital and configurable LED driver ICs have a two-stage architecture, which eases the implementation of flicker standards that are due to be introduced, says Infineon Technologies.
The XDPL8220’s primary side control saves extra components, reducing cost and increasing reliability, claims the company. 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 (ECG), while a standby power of less than 70mW reduces power consumption in the non-active mode, while still reacting to external events or user requests.
Advanced control algorithms provide the possibility 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.
