Summary and Features
•
•
Low cost, low part count solution: requires only 19 components
Integrated LinkSwitch-XT safety and reliability features:
• Accurate (± 5%), auto-recovering, hysteretic, thermal shutdown function keeps PCB
temperature below safe levels under all conditions
• Auto-restart protects against output short-circuits and open feedback loops
• > 3.2 mm creepage on IC package enables reliable operation in high humidity and
high pollution environments
•
EcoSmart® – meets all existing and proposed international energy efficiency standards
such as China (CECP) / CEC / EPA / AGO / European Commission
• No-load consumption 110 mW at 265 VAC
• 61.5 % active-mode efficiency (exceeds CEC requirement of 55.2 %)
E-Shield™ transformer construction and frequency jitter enable this supply to meet
EN550022 & CISPR-22 Class B EMI with >10 dBµV of margin
Meets IEC61000-4-5 Class 3 AC line surge
