11-Feb-13RDR-347 <strong>12.6</strong> W Dimmable LED Driver Using LYT4313E16 No Active Pre-Load OptionWithout the active pre-load circuit connected on the secondary output the natural highefficiency per<strong>for</strong>mance of LYTSwitch is achieved. Although minimum dim current maybehigher <strong>for</strong> <strong>TRIAC</strong> dimmers with a high minimum conduction angle (>40º), high dim ratiocan be achieved with most dimmers that were designed properly (see section 16.9-10 <strong>for</strong>dimming per<strong>for</strong>mance).16.1 SchematicFigure 75 – No Active Pre-Load Schematic.Page 55 of 78Power IntegrationsTel: +1 408 414 9200 Fax: +1 408 414 9201www.powerint.com
