LinkSwitch-XT2 Offline Flyback Switcher IC Family From Power Integrations Delivers High Accuracy and Efficiency



Power Integrations introduced its LinkSwitch-XT2 family of offline, low-power converter ICs offering accuracy, efficiency and no-load performance. LinkSwitch-XT2 ICs target isolated and non-isolated flyback applications in which accurate regulation of output voltage and current are important. The new ICs can deliver up to 6.1 watts in wide-input range designs, and up to 9.2 watts for 230 VAC open-frame applications.
Designed for flyback topologies, the LinkSwitch-XT2 family delivers designs that exhibit current and voltage regulation of better than -/+ 3% and typical efficiency above 80%. LinkSwitch-XT2 ICs consume less than 10 mW in no-load conditions. High (132 kHz) operating frequency enables the use of small power transformers, while the programmable current limit (ILIM) function enables further transformer optimization.
LinkSwitch-XT2 converters combine a 725 V power MOSFET with control circuitry on a single silicon die. Integrated safety and reliability features include input overvoltage protection, hysteretic thermal shutdown for over-temperature protection, and auto-restart for output short-circuit, overvoltage and open-loop protection.
Comments senior product marketing manager Silvestro Fimiani: “The accuracy, small size, efficiency and excellent no-load performance of LinkSwitch-XT2 ICs makes them ideal for small appliances such as microwave ovens, IoT applications, utility meters, industrial and smart-home installations.”
