Product Highlights

EcoSmart™- Energy Effcient

• Multi-mode control maximizes effciency over full load range

• No-load consumption below 30 mW at 230 VAC (LNK67xx)

• >75 effciency with 1 W input at 230 VAC

• >50 effciency with 0.1 W input at 230 VAC

High Design Flexibility for Low System Cost

• Dramatically simplifes 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 flter cost

• Fully integrated soft-start for minimum start-up stress

• 725 V MOSFET simplifes 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

• Output short-circuit protection (SCP)

• Output overload/over-current protection (OPP, OCP)

• Optional extended shutdown delay time

• Output overvoltage protection (OVP), auto-restart or latching

• Line brown-in/out protection (line UV)

• Line overvoltage (OV) shutdown extends line surge withstand

• Accurate thermal shutdown (OTP), hysteretic or latching
