LNK626PG LinkSwitch CV Off Line Switcher AC-DC Converter IC 

LNK623-626 LinkSwitch-CV Family Energy-Efficient, Off-line Switcher With Accurate Primary-Side Constant-Voltage (CV) Control

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.
