Lamp dimmers and their circuits must be compact, energy efficient and able to operate reliably in confined spaces. Lamp brightness is varied by controlling the conduction time of each half-cycle of ...

To understand the technology associated with practical LED dimming we first have to look at the technology associated with triac-based incandescent lamp dimmers. The typical triac lamp dimmer circuit ...

Power Integrations announced a new reference design (RDK-251) for a 5-watt offline LED driver that includes flicker-free TRIAC dimming and single-stage power factor correction (PFC). Power ...

The circuit was designed to create a lamp that incorporates the operation of a touch dimmer using S566B integrated circuit manufactured by Siemens. S566B – a lamp dimmer integrated circuit produced by ...
