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

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
