LinkSwitch
0-4 W Designs Delivering Switcher Benefits at Linear Cost
Typical Application
Description:
- Extremely simple circuit configuration
- Primary based CV/CC solution eliminates 10 to 20 secondary components for low system cost
- Universal input range allows worldwide operation
- Up to 70% reduction in power dissipation-reduces enclosure size significantly
- System level thermal and current limit protection
- Up to 75% lighter power supply reduces shipping cost
- Consumes <300 mW at 265 VAC with no load
Features:
LNK500
- Optimized for linear replacement in CV only designs
- Lowest cost solution for linear replacement CV/CC chargers with =±25% CC tolerance
- Recommended for cost sensitive applications in larger systems with existing EMI filtering
LNK501
- Optimum choice for CV/CC chargers with =±20% CC tolerance
- Recommended for charger/adapters where the best CV/CC tolerance is required
LNK520
- Optimized for bias winding feedback and EMI reduction
- Very low cost CV/CC implementation
- Recommended for both stand-alone charger/adapter applications and larger systems where EMI reduction is required
Applications:
- Linear transformer replacement in all = 4 W AC-DC applications
- Chargers for cell phones, cordless phones, PDAs, digital cameras, MP3/portable audio devices, shavers, etc.
- Home appliances, white goods and consumer electronics
- TV standby and other auxiliary supplies
