Check out the GaN-based, 6.6kW, bidirectional on-board charger reference design.

The industry's first automotive GaN FET with integrated gate drivers, protection, reporting and active power management, TI's LMG3522R030-Q1 comes in a top-cooled surface-mount package to simplify manufacturing and heat dissipation. The C2000 MCU ensures smooth monotonic start-up of the power factor correction (PFC) output.

The combination of GaN FETs and C2000 MCUs enables industry-leading 500kHz resonant frequency and 59% smaller magnetics with a 6.6kW on-board charger. The REF35 series voltage references improve system reliability with excellent quiescent current and long-term drift performance of 0.68μA.
