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 (LNK677x)

? 650 V MOSFET for lowest system cost (LNK676x/LNK666x)

? Fast transient response family option (LNK666x)

Extensive Protection Features

? Auto-restart limits power delivery to 3% during overload faults
