LINK®-II: THE SOLUTION FOR MAINS-FED CONSTANT CURRENT SOURCES

With its brand new LinkSwitch®-II family, POWER INTEGRATIONS is especially targeting constant current and constant voltage applications, meaning battery chargers, adapters and LED power supplies especially. POWER INTEGRATIONS emphasized simplicity in the design of the new devices, as well as efficiency for the complete converter stage. By eliminating the need for an optocoupler on the secondary side, as well as a compensation network, yet still achieving tight current and voltage tolerances, the LinkSwitch®-II family offers equipment manufacturers a cost-saving alternative.
We also invite customers to take advantage of CODICO’s design know-how!

Highlights:
* Auto restart
* Hysteretic thermal shutdown
* Compensates for transformer inductance tolerances and cable losses
* Frequency jittering for improved EMC behavior
* No-load consumption: 200mW, and down to <30mW with external bias winding
* Suitable for a rated power of 2.5W - 6W
* A design accelerator kit is available
