Summary and Features
• EcoSmart
®
– Meets all existing and proposed harmonized energy efficiency
standards including: CECP (China), CEC, EPA, AGO, European Commission
• No-load consumption 140 mW at 265 VAC (no bias winding required)
• > 75% active-mode efficiency (exceeds standards requirement of 71%)
• BP/M capacitor value selects MOSFET current limit for greater design flexibility
• Output overvoltage protection (OVP) using primary bias winding sensed
shutdown feature
• Tightly toleranced I
2
f parameter (–10%, +12%) reduces system cost:
• Increases MOSFET and magnetics power delivery
• Reduces overload power, which lowers output diode and capacitor costs
• Integrated TinySwitch-III Safety/Reliability features:
• Accurate (± 5%), auto-recovering, hysteretic thermal shutdown function
maintains safe PCB temperatures under all conditions
• Auto-restart protects against output short circuit and open loop fault
conditions
• > 3.2 mm creepage on package enables reliable operation in high humidity
and high pollution environments
• Meets EN550022 and CISPR-22 Class B conducted EMI with >12 dBµV margin
• Meets IEC61000-4-5 Class 3 AC line surge
