LNK626PG dip-7

Микросхема LNK626 (LNK626PG)

LNK626 - Energy-Efficient, Off-line Switcher with Accurate Primary-side Constant-Voltage (CV) Control, DIP-7

 

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

 

EcoSmart™– Energy Efficient

• 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

 

Green Package

• Halogen free and RoHS compliant package

 

Applications

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