Product Details
LYTSwitch-4 series High Power LED Driver AC-DC Converters
The Power Integrations LYTSwitch-4 family of off-line AC-DC single-stage converters are designed for high-power LED driver applications. They integrate control and drive circuits and power factor correction in a single package and are available in both dimming and non-dimming versions.
• High line voltage operation: 160-308 Vac
• Better than ±5% constant current regulation
• Up to 92% efficiency in typical applications
• High power factor >0.9
• Easily meets EN61000-3-2
• Less than 10% THD in optimized designs
• 132 kHz switching frequency permits use of small low-cost magnetics
• No primary side aluminium electrolytic bulk capacitors required
LTY432x types only:
• TRIAC dimmable to less than 5% of full output
• Fast start-up: <250 ms at full brightness, <1s at 10% brightness
