Summary and Features
•
•
•
EcoSmart® – meets all existing and proposed harmonized energy efficiency
standards including: CECP (China), CEC, EPA, AGO, European Commission
•
•
No-load power consumption 200 mW at 265 VAC
81.8% active-mode efficiency (exceeds requirement of 80.2%)
Tight tolerance I2f parameter (-10%/+12%) reduces system cost:
•
•
•
Increases MOSFET and magnetics power delivery
Reduces worst-case overload power, which lowers component costs
Allows small EE25 core size
Integrated PeakSwitch safety/reliability features:
•
Accurate (± 5%), auto-recovering, hysteretic thermal shutdown function
maintains safe PCB temperatures under all conditions
•
•
•
Auto-restart protects against output short circuits and open feedback loops
Adaptive current limit reduces output overload power
Programmable smart AC line sensing provides latching shutdown during
short circuit, overload and open loop faults and prevents power ON/OFF
glitches during power down or brownout
•
•
Meets EN55022 and CISPR-22 Class B conducted EMI with >14 dBµV margin
Meets IEC61000-4-5 Class 3 AC line surge
