Product Highlights
DramatICally Simplifi es 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
fl exibility
? Frequency jittering greatly reduces EMI fi lter 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 fi eld
? Meets HV creepage requirements between Drain and all other
pins, both on the PCB and at the package
EcoSmart? – Energy Effi cient
? No-load consumption <200 mW at 230 VAC and down to
below 70 mW with optional external bias
? Easily meets all global energy effi ciency regulations with no
added components
? ON/OFF control provides constant effi ciency down to very light
loads – ideal for mandatory EISA and ENERGY STAR 2.0
regulations
? No primary or secondary current sense resistors – maximizes
effi ciency
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
Description
The LinkSwitch-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.
