RDR-347 12.6 W Dimmable LED Driver Using LYT4313E11-Feb-1315 Line SurgeThe unit was subjected to ±2500 V 100 kHz ring wave and ±500 V differential surge at120 VAC using 10 strikes at each condition. A test failure was defined as a nonrecoverableinterruption of output requiring supply repair or recycling of input voltage.Level(V)InputVoltage(VAC)InjectionLocationInjectionPhase(°)+2500 120 L1, L2 0-2500 120 L1, L2 0+2500 120 L1, L2 90-2500 120 L1, L2 90Type100 kHz RingWave (500 A)100 kHz RingWave (500 A)100 kHz RingWave (500 A)100 kHz RingWave (500 A)Test Result(Pass/Fail)PassPassPassPassLevel(V)InputVoltage(VAC)InjectionLocationInjectionPhase(°)TypeTest Result(Pass/Fail)+500 120 L1, L2 0 Surge (2 ) Pass-500 120 L1, L2 0 Surge (2 ) Pass+500 120 L1, L2 90 Surge (2 ) Pass-500 120 L1, L2 90 Surge (2 ) PassFigure 74 – 500 V Differential Line Surge at 90º Injection Phase.CH1: U1 VC5 (
11-Feb-13RDR-347 12.6 W Dimmable LED Driver Using LYT4313E16 No Active Pre-Load OptionWithout the active pre-load circuit connected on the secondary output the natural highefficiency performance of LYTSwitch is achieved. Although minimum dim current maybehigher for TRIAC 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 fordimming performance).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
