LinkSwitch-HP Family
Energy Efficient, High-Power Off-Line Switcher
With Accurate Primary-Side Regulation (PSR)
Product Highlights
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
CONTROL
• 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)

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
