Dramatically simplifies low power power supply designs by eliminating an optocoupler and secondary control circuitry.
Typical Application/Performance – Not a Simplified Circuit (a) and Output Characteristic Envelope (b).
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 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.
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
· Standby and auxiliary supplies
· Home appliances, white goods and consumer electronics
