LNK626DG-TL Common IC Chips 8.5W 85-265VAC PMIC AC DC Converter Voltage Control

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.
