Power Integrations has announced an AEC-Q100-qualified version of its LinkSwitch-TN2 switcher IC for buck or non-isolated flyback applications.
Featuring an integrated 750V MOSFET, the new automotive-qualified LinkSwitch-TN2 IC provides simple and reliable power for EV sub-systems connected to the high-voltage bus, including HVAC, climate control, battery management, battery heater, DC-DC converter and on-board charger systems. The surface-mount device requires no heatsink, needs few external components and occupies a very small PCB footprint.
The seven watt (flyback) / 360 mA (buck) LinkSwitch-TN2 has a wide input voltage range of 60 to 550VDC, efficiently supporting the 400VDC bus commonly seen in electric vehicle applications. The new power supply IC provides accurate regulation of better than +/-5% across line voltage, load, temperature and component tolerances.
Comments Power Integrations’ Product Marketing Manager Edward Ong, said: “Our automotive switcher ICs reduce size while increasing the reliability and robustness of automotive sub-systems. By supplying auxiliary systems directly from the high-voltage bus with a LinkSwitch-TN2 power supply, automotive engineers can reduce the requirement for the conventional 12V distributed rail, saving assembly and material cost.”
Samples of the LNK3206GQ automotive-qualified LinkSwitch-TN2 IC are available now with prices starting at $0.84 in 10,000-piece quantities.
