LinkSwitch-II Product Family

• 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 trans-former size

• 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

Applications

• Chargers for cell/cordless phones, PDAs, MP3/portable audio devices, adapters
• LED drivers, etc.
