PrimAccurate™ Technology
Accurate Primary-Side Control
 PrimAccurate™ technology
Transformer
 Accurate:
-
Rectifier
Rectifier
Proprietary approach ensures
accurate control of voltage and current
SecondarySide
Controller
Primary Side Drive
and Control
Opto-isolator
 Primary-side control:
-
Reduces BOM cost by eliminating:
 Opto-isolator
 Secondary-side regulator
 Many discrete parts
Lower Cost, More Reliable,
Better Performance

Reliability Advantages of PrimAccurate™
 All components and solder joints are a potential failure
point
- Eliminating any components increases reliability
 Opto-isolate has lower MTBF than most components
- Eliminating the opto-isolator improves system-level MTBF

Flickerless™ Technology
 Flickerless™ technology
 “Intelligent digital dimming”
-
Compatible with vast majority of
installed wall dimmers (TRIAC, digital)
-
Patented digital dimming control
enables “smart” dimmer detection
 Eliminates 2X line frequencies:
-
Ficker-free dimming from 1-100% with
tight +/-5% LED current regulation
Compatible with Broad Range of Dimmers
AND Eliminates Harmful Flicker
