Cost Effective Linear/RCC Replacement
- • Lowest cost and component count, constant voltage, constant current (CV/CC) solution
- • Extremely simple circuit configuration
- • Up to 75% lighter power supply reduces shipping cost
- • Primary based CV/CC solution eliminates 10 to 20 secondary components for low system cost
- • Combined primary clamp, feedback, IC supply, and loop compensation functions – minimizes external components
- • Fully integrated auto-restart for short circuit and open loop fault protection – saves external component costs
- • 42 kHz operation simplifies EMI filter design
- • 3 W output with EE13 core for low cost and small size 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 clamp capacitor
- • Controlled current in CC region provides inherent soft-start
- • Optional opto feedback improves output voltage accuracy Eco Smart ™ – 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
