EcoSmart™- Energy Efficient
• Multi-mode control maximizes efficiency over full load range
• No-load consumption below 30 mW at 230 VAC (LNK67xx)
• >75% efficiency with 1 W input at 230 VAC
• >50% efficiency with 0.1 W input at 230 VAC
High Design Flexibility for Low System Cost
• Dramatically simplifies power supply designs
• Eliminates optocoupler and all secondary control circuitry
• ±5% or better output voltage tolerance
• 132 kHz operation reduces transformer and power supply size
• Accurate programmable current limit
• Compensation over line limits overload power
• Frequency jittering reduces EMI filter cost
• Fully integrated soft-start for minimum start-up stress
• 725 V MOSFET simplifies meeting derating requirements
• 650 V MOSFET for lowest system cost (LNK676x/LNK666x)
• Fast transient response family option (LNK666x)
