LNK626DG-TL Common IC Chips 8.5W 85-265 VAC PMIC ACDC Converter Voltage Control
> Applications
• DVD/STB
• Adapters
• Standby and auxiliary supplies
• Home appliances, white goods and consumer electronics
• Industrial controls
> Features
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
• 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 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
> Description
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.
