Product Details

Description

The LinkSwitch-CV dramatically simplifies CV power supply design with tight CV requirements and by eliminating an optocoupler and secondary control circuitry. The device introduces a revolutionary control technique to provide very tight output voltage regulation, along with input voltage variations and temperature.

The device incorporates a 725 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.

Product Highlights

Dramatically Simplifies CV Converters

  • Eliminates optocoupler and all secondary CV control circuitry
  • Eliminates bias winding supply – IC is self biasing

Advanced Performance Features

  • 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

Advanced Protection/Safety Features

  • Auto-restart protection reduces delivered power by <95% for output short circuit and all control loop faults (open and shorted components)
  • Hysteretic thermal shutdown – automatic recovery reduces power supply returns from the field
  • Meets HV creepage requirements between Drain and all other pins, both on the PCB and at the package
  • 725 V power MOSFET

Applications

  • DVD/STB
  • Adapters
  • Standby and auxiliary supplies
  • Home appliances, white goods and consumer electronics
  • Industrial controls
