LNK623PG

instructions

LinkSwitch - CV by eliminating the light coupling and secondary control circuit, can greatly simplify have strict request for constant pressure constant voltage power supply design.The device adopts the innovative control technology, can provide extremely as the input voltage and temperature change output voltage regulation strictly.

The components in a monolithic IC used a 725 V power MOSFET, novel on/off control of state machine, a high voltage switch to the bias current source, frequency jitter, a week deadline flow and hysteresis heat off circuit.

The product features

The design of constant pressure transducer is greatly simplified

• Save the light coupling constant voltage control circuit and all secondary side
• Eliminating offset winding power - IC from bias

The performance of the advanced features

• Temperature drift compensation peripheral components
• The adjustment of the proprietary technology makes IC parameters tolerance is very strict
• The frequency jitter technology greatly reduces the cost of EMI filter
• Through the external resistors selection/adjustment for the tougher output tolerance

Advanced protection/security features

• Automatic restart protection function in the output short circuit and control circuit fault (element open circuit and short circuit conditions the output power can be reduced by more than 95%
• Hysteresis heat off - automatic recovery function can reduce the repair rate of power supply
• No matter on the PCB board or on the packaging, ensure high pressure drain and satisfies the requirement of high voltage creepage between all other pins
• The 725 V power MOSFET

application

• DVD/set-top box
• The adapter
• Standby and auxiliary power supply applications
• Household appliances, white goods and consumer electronics
• Industrial control
