LinkSwitch-CV Family  
Energy-Efficient, Off-line Switcher with Accurate  
Primary-side Constant-Voltage (CV) Control  
Product Highlights  
*
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

LinkSwitch-CV  
• Frequency jittering greatly reduces EMI filter cost  
• Even tighter output tolerances achievable with external resistor  
selection/trimming

VO  
Advanced Protection/Safety Features  
• Auto-restart protection reduces delivered power by >915 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  
IO  
PI-5196-080408  
(b) Output Characteristic  
• 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  
Figure 1. Typical Application Schematic (a) and Output Characteristic Envelope (b).  
*Optional with LNK623-624PG/DG. (see Key Application Considerations section for  
clamp and other external circuit design considerations).  
• 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

section for more information).  
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.  
3. Packages: P: DIP-8C, D: SO-8C.  
LinkSwitch-CV provides excellent cross-regulation for multiple-  
output flyback 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.
