The TLP265J consists of a non-zero crossing photo triac, and the TLP266J consists of a zero crossing photo triac, and both are optically coupled to a gallium arsenide infrared emitting diode. Using a ...
Two new triac-output optocouplers developed by Toshiba Electronics Europe provide reinforced insulation and low LED trigger currents up to 3 mA. Two new triac-output optocouplers developed by Toshiba ...
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).
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 ...
