The LinkSwitch-XT2SR family of non-isolated flyback switcher ICs brings a new level of integration and efficiency to small open-frame power supplies up to 15 W. Incorporating a synchronous rectifier driver, these constant-voltage ICs reduce component count and achieve up to 90% efficiency.
LinkSwitch-XT2SR devices consume less than 5 mW in no-load, easily surpassing the newest requirements of the European Union’s Energy-Related Products (ErP) Directive. They deliver 250 mW to the load within the 300 mW ErP allowance, enabling more system functionality to operate in standby mode for smallSource: Power Integrations appliances, home and building automation, as well as a range of industrial applications.
Three new design example reports demonstrate the exceptional performance and versatility of LinkSwitch-XT2SR ICs.
