LinkSwitch Family

The LinkSwitch™ families of ICs are low power offline switchers that incorporate both a high-accuracy controller and high voltage MOSFET into a single low pin-count package. LinkSwitch devices use simple ON/OFF controllers, which are highly suitable for applications where light-load/no-load efficiency is a key specification requirement. They are optimized for isolated flyback power supplies and, in a non-isolated variant, for low-current offline buck applications. The LinkSwitch families leverage a variety of feedback strategies such as Primary Side Regulated (PSR), classical opto feedback and direct measurement of the output voltage.

LinkSwitch ICs are used in a number of applications such as: chargers, adapters, large and small appliances, consumer audio/video systems, utility meters, and a wide variety of industrial bias supplies.
