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 LED low power applications such as small bulbs. They are also extremely useful in bias supplies and for standby in larger applications and logic drivers for smart lighting.
