Overview

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 LNK623/4. LinkSwitch-CV provides excellent cross-regulation for multiple-output flyback applications such as DVDs and STBs. A 725 V power MOSFET and ON/OFF control state machine, self-biasing, frequency jittering, cycle-by-cycle current limit, and hysteretic thermal shutdown circuitry are all incorporated onto one IC.

Applications

DVD/STB
Adapters
Standby and auxiliary supplies
Home appliances, white goods and consumer electronics
Industrial controls

Key features

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
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
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
No primary or secondary current sense resistors – maximizes efficiency
Halogen free and RoHS compliant package
