The LinkSwitchTM-CV dramatically simplifies low power, constant voltage (CV) converter design through a revolutionary control technique which eliminates the need for both an optocoupler and secondary CV control circuitry while providing very tight output voltage regulation. The combination of proprietary IC trimming and E-Shield™ transformer construction techniques enables Clampless™ designs with the LinkSwitch-CV LNK624.
Feature
- Eliminates optocoupler and all secondary CV control circuitry
- Eliminates bias winding supply - IC is self biasing
- Compensates for external component temperature variations
- Very tight IC parameter tolerances using proprietary trimming technology
- Frequency jittering greatly reduces EMI filter cost
- 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
- No-load consumption <200 mW at 230 VAC and down to below 70 mW with optional external bias
- Easily meets all global energy efficiency regulations with no added components
- ON/OFF control provides constant efficiency down to very light loads - ideal for mandatory EISA and ENERGY STAR 2.0 regulations
