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
