LinkSwitch-CV

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).

   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 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.

   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

   Applications

· DVD/STB

· Adapters

· Standby and auxiliary supplies

· Home appliances, white goods and consumer electronics
