Notes:
1. Minimum continuous power in a typical non-ventilated enclosed adapter
measured at +50 °C ambient.
2. Maximum practical continuous power in an open frame design with adequate
heatsinking, measured at 50 °C ambient (see Key Application Considerations
section for more information).
3. Packages: P: DIP-8C, D: SO-8C.
Product Highlights
Dramatically Simplies 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
exibility
Frequency jittering greatly reduces EMI 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 eld
Meets HV creepage requirements between Drain and all other
pins, both on the PCB and at the package
EcoSmart – Energy Efcient
No-load consumption <200 mW at 230 VAC and down to
below 70 mW with optional external bias
Easily meets all global energy efciency regulations with no
added components
ON/OFF control provides constant efciency down to very light
loads – ideal for mandatory EISA and ENERGY STAR 2.0
regulations
No primary or secondary current sense resistors – maximizes
efciency
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 simplies 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 yback applications such as DVDs and STBs. A 700 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.
