The 65W gallium nitride charger scheme INN3378C+INN3365C65W gallium nitride charger scheme uses INN3378C+INN3365C as the main control chip, using PowiGaN technology. The chip is equipped with a PWM controller, high-voltage MOS, synchronous rectification controller, etc., with very high integration, and uses digital bus control for voltage regulation.
This charger adopts the Onbao fast charging power supply scheme internally and the OB2631U+OB2013B highly integrated switch power supply scheme, with simplified peripheral components. The protocol chip comes from Tiandeyu and uses JD6606S+FP6601A protocol chips for USB-C and USB-A interfaces, respectively. The chip is equipped with comprehensive protection functions, making charging safer.
