LinkSwitch-II Product Family

Energy-Efficient, Accurate CV/CC Switcher for Adapters and Chargers

Image of Power Integrations LinkSwitch-IIPower Integrations' LinkSwitch-II 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 tight output voltage and current regulation, compensating for transformer and internal parameter tolerances along with input voltage variations.

The device incorporates a 700 V power MOSFET, a novel On/Off control state machine, a high voltage switched current source for self biasing, frequency jittering, cycle-by-cycle current limit and hysteretic thermal shutdown circuitry onto a monolithic IC.

Performance Features Safety 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 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.
