The LM3445 from National Semiconductor enables a full 100:1 range of offline, uniform, flicker-free dimming for high-brightness LEDs with a conventional TRIAC forward or reverse phase-control wall ...
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 ...
