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 I2f 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
