Power Integrations introduced its LinkSwitch-XT2 family of offline, low-power converter IC’s offering high accuracy, high efficiency and excellent no-load performance. LinkSwitch-XT2 IC’s 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 IC’s 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. LinkSwitch-XT2 IC’s come in three packages: P-package (DIP-8C), D-package (SO-8C), and G-package (SMD-8C) and are priced at $0.40 in 10,000-piece quantities. More information, including reference design DER-578, which details a 5 V 500 mA power supply, is available from the Power Integrations website.
Power Integrations, Inc. designs, develops and markets analog and mixed-signal integrated circuits (ICs) and other electronic components and circuitry used in high-voltage power conversion. The Company's products are used in power converters that convert electricity from a high-voltage source to the type of power required for a specified downstream use. The Company's ICs used in alternating current (AC)-direct current (DC) power supply convert high-voltage AC from a wall outlet to the low-voltage DC required by electronic devices. The Company offers a range of products, such as TOPSwitch, TinySwitch, LinkSwitch and Hiper families. It also offers CapZero and SenZero families. The Company offers a range of high-voltage gate-driver products sold under the SCALE and SCALE-II product-family names. The BridgeSwitch family of products is a family of motor-driver ICs addressing brushless DC (BLDC) motor applications up to approximately 400 watts.
