6.6-kW OBC with GaN, C2000™ real-time MCUs and REF35

Learn more about the GaN-based, 6.6-kW, bidirectional, onboard charger reference design.

Our industry first automotive GaN FET with integrated gate driver, protection, reporting and active power management, LMG3522R030-Q1, features a top cooled surface mount package to simplify production and heat dissipation. The C2000 MCU ensures smooth monotonic start-up of power factor correction (PFC) output. 

Together, the GaN FET and C2000 MCU can enable an industry-highest 500kHz resonant frequency and 59% smaller magnetics in a 6.6-kW on-board charger. The REF35 series voltage reference features an impressive 0.68-µA quiescent current and excellent long-term drift performance for improved system reliability.
