Space-saving buck/flyback switcher ICs target 400Vdc EV applications

POWER INTEGRATIONS LinkSwitch-TN2 switcher IC for buck or non-isolated flyback applications is AEC-Q100 automotive-qualified. Featuring an integrated 750 V MOSFET, device 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. Surface-mount device requires no heatsink, needs few external components and occupies a very small pcb footprint. The 7 W (flyback) / 360 mA device has a wide input voltage range of 60Vdc to 550 Vdc, efficiently supporting the 400Vdc bus commonly seen in electric vehicle applications.
