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 ...
This document thoroughly discusses about random phase crossing triac drivers and their most common applications. It will start off with a basic electrical description of triac drivers. Following then ...
Fairchild Semiconductor introduced the FL7730 single-stage primary side regulation (PSR) controller with power factor correction (PFC) for triac and analog dimming compatibility. The FL7730 circuit is ...
