- Power Integrations’ new IC provides a wide input voltage range, thus supporting the power bus present in electric vehicles
- The ICs help in reducing size while increasing the reliability and robustness
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 750 V 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 7 W (flyback) / 360 mA (buck) LinkSwitch-TN2 has a wide input voltage range of 60 VDC to 550 VDC and efficiently supports the 400 VDC bus commonly seen in electric vehicle applications. The new power supply IC provides accurate regulation of better than +/-5 per cent across line voltage, load, temperature and component tolerances.
“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 12 V distributed rail, saving assembly and material cost,” said Edward Ong, product marketing manager at Power Integrations.
Samples of the LNK3206GQ automotive-qualified LinkSwitch-TN2 IC are now available.
