LinkSwitch CV
Power Integrations' LinkSwitch-CV dramatically simplifies CV power supply design by eliminating an optocoupler and secondary control circuitry
Power Integrations' LinkSwitch-CV dramatically simplifies CV power supply design with tight CV requirements 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 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.
- Compensates for external component temperature variations
- Very tight IC parameter tolerances using proprietary trimming technology
- Continuous and/or discontinuous mode operation for design flexibility
- Frequency jittering greatly reduces EMI filter cost
- Even tighter output tolerances achievable with external resistor selection/trimming
- 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
- DVD/STB
- Adapters
- Standby and auxiliary supplies
- Home appliances, white goods and consumer electronics
- Industrial controls
- Eliminates optocoupler and all secondary CV control circuitry
- Eliminates bias winding supply: IC is self biasing
