LNK624DG-TL

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.

• 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 <gt/>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 <lt/>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
