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
