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
