Non-insulated power supplies are often required when a power semiconductor, which has to be controlled using this supply, has its drive reference connected to the mains (line or neutral terminal).
This design example report is a 7 W TRIAC dimmable, high efficiency, power factor corrected, non-isolated buck LED driver employing LYTSwitch™-3 LYT3315D. It operates in an input voltage ranging from ...
Triacs are used to control ac mains loads in home appliances, and commercial and industrial equipment. In the majority of applications, the triac will dissipate sufficient power to make thermal ...
