Power Integrations has launched an AEC-Q100 qualified version of its LinkSwitch™-TN2 switching IC s for non-isolated flyback or buck applications. Featuring an integrated 750V MOSFET, the new automotive-qualified LinkSwitch-TN2 IC provides simple, reliable power for high-voltage bus-connected electric vehicle systems - ventilation and air conditioning, battery management and heating, DC-DC converter, and in-vehicle battery charging systems. The surface-mount device does not need heatsinks, requires only a few external components and has a very small circuit board footprint.

Edward Ong, product marketing manager at Power Integrations, explains why this new version is useful for designers: "Our automotive switching ICs reduce the footprint while increasing the reliability of the vehicle's auxiliary systems. By powering these directly from the high-voltage bus via a LinkSwitch-TN2, designers can simplify the requirement on the conventional 12 V distributed line, reducing material and assembly costs."

The 7 W (flyback) / 360 mA (buck) LinkSwitch-TN2 operates over a wide range of input voltages - from 60 to 550 V DC, efficiently supporting the 400 V DC bus often found in electric vehicles. This new power supply IC offers precise regulation of better than +/-5% on various parameters - line voltage, load, temperature and component tolerances.
