Description
The LinkSwitch™-3 family of ICs dramatically simplifies low power CV/CC charger designs by eliminating an optocoupler and secondary control circuitry. The device introduces a revolutionary control technique to provide very accurate output voltage and current regulation, compen-sating for transformer and internal parameter tolerances along with input voltage variations.
Dramatically Simplifies CV/CC Converters
• Eliminates optocoupler and all secondary CV/CC control circuitry
• Eliminates all control loop compensation circuitry
• Compensates for transformer inductance tolerances
• Compensates for input line voltage variations
• Compensates for cable voltage drop
• Compensates for external component temperature variations
• Very accurate IC parameter tolerances using test trimming technology
• Frequency jittering greatly reduces EMI filter cost
• Programmable switching frequency up to 85 kHz to reduce transformer size
• Minimum operation frequency fixed to improve transient load response
• Auto-restart protection reduces power delivered by >90% 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
• Easily meets all global energy efficiency regulations with no added components
• No-load consumption at 230 VAC input with bias winding <10 mW for LNK64x4-LNK64x6 and <30 mW for LNK64x7-LNK64x8
• ON/OFF control provides constant efficiency down to very light loads – ideal for CEC regulations
• No current sense resistors – maximizes efficiency
• Halogen free and RoHS compliant package
• Chargers for cell/cordless phones, PDAs, MP3/portable audio devices, adapters, etc.
