LYTSwitch-5 series LED Driver AC-DC Converters
The LYTSwitch-5 family of AC-DC Converters from Power Integrations is ideal for single-stage power factor corrected constant current LED applications, equally suited for lamps, tubes or ballasts. These highly integrated devices incorporate a discontinuous mode, variable frequency, variable on-time controller, and a high-voltage power MOSFET in a single compact package and include advanced thermal management and protection circuitry.
• Efficiency >90% in optimized designs
• Power Factor >0.9
• Constant current regulation accuracy better than ±3%
• Low THD, <10% with typical input and output conditions
• High switching frequency and DCM allow compact magnetics
• Supports buck, buck-boost, tapped-buck, boost, isolated and non-isolated flyback topologies
• No electrolytic bulk capacitors or opto-isolators for increased lifetime and reliability
• Input and output overvoltage protection
• Open-loop protection
• Thermal control with fold-back allows output light delivery at high ambient temperatures
• Hysteretic shutdown provides protection during fault conditions
