Dramatically Simplifies CV/CC Converters
• Eliminates optocoupler and all secondary CV/CC control circuitry
• Eliminates all control loop compensation circuitry
Advanced Performance Features
• Compensates for transformer inductance tolerances
• Compensates for input line voltage variations
• Compensates for cable voltage drop (LNK61X series)
• Compensates for external component temperature variations
• Very tight IC parameter tolerances using proprietary trimming
technology
• Frequency jittering greatly reduces EMI filter cost
• Even tighter output tolerances achievable with external resistor
selection/trimming
• Programmable switching frequency up to 85 kHz to reduce transformer
size
Advanced Protection/Safety Features
• Auto-restart protection reduces power delivered by >95% for output
short-circuit and control loop faults (open and shorted components)
• Hysteretic thermal shutdown – automatic recovery reduces power
supply returns from the field
• Meets high-voltage creepage requirements between DRAIN and all
other pins both on the PCB and at the package
EcoSmart™– Energy Efficient
• Easily meets all global energy efficiency regulations
• No-load consumption below 30 mW at 230 VAC with optional
external bias winding
• ON/OFF control provides constant efficiency down to very light loads
– ideal for CEC and ENERGY STAR 2.0 regulations
• No current sense resistors – maximizes efficiency
Green Package
• Halogen free and RoHS compliant package
Applications
• Chargers for cell/cordless phones, PDAs, MP3/portable audio
devices, adapters, LED drivers, etc.
