Cost Effective Linear/RCC Replacement
• Lowest cost and component count, constant voltage (CV)
or constant voltage/constant current (CV/CC) solutions
• Optimized for bias winding feedback
• Up to 75% lighter power supply reduces shipping cost
• Primary based CV/CC solution eliminates 10 to 20
secondary components for low system cost
• Fully integrated auto-restart for short circuit and open loop
fault protection – saves external component costs
• 42 kHz operation with optimized switching characteristics
for significantly reduced EMI
Much Higher Performance Over Linear/RCC
• Universal input range allows worldwide operation
• Up to 70% reduction in power dissipation – reduces
enclosure size significantly
• CV/CC output characteristic without secondary feedback
• System level thermal and current limit protection
• Meets all single point failure requirements with only one
additional bias capacitor
• Controlled current in CC region provides inherent soft-start
• Optional opto feedback improves output voltage accuracy
EcoSmart ™ – Extremely Energy Efficient
• Consumes <300 mW at 265 VAC input with no load
• Meets California Energy Commission (CEC), Energy Star,
and EU requirements
• No current sense resistors – maximizes efficiency
Applications
• Linear transformer replacement in all ≤3 W applications
• Chargers for cell phones, cordless phones, PDAs, digital
cameras, MP3/portable audio devices, shavers, etc.
• Home appliances, white goods and consumer electronics
• Constant output current LED lighting applications
• TV standby and other auxiliary supplies
