LinkSwitch

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. LinkSwitch-XT2 and LinkSwitch-TN2 are available with 900 V primary MOSFETs for three-phase industrial power supplies and high-quality consumer products destined for regions with high and unstable mains grids, tropical regions with frequent lightning strikes or any area where high-energy ring-waves and surges are prevalent.

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.
