The following Yingjixin INN3378C+INN3365C 65W gallium nitride charger is a 2C1A product with two TYPE-C interfaces and one USB interface. The total output power is 65W, and a single port supports 65W fast charging. Below is a breakdown and explanation of this product.

Analysis of the 65W gallium nitride charger scheme. The main control chip of the Ingot chip is INN3378C, which adopts PowiGaN technology. The chip is equipped with a PWM controller, high-voltage MOS, synchronous rectification controller, etc., with very high integration, and adopts digital bus control for voltage regulation. Under wide voltage range conditions, the enclosed enclosure can output 55W of power, which can be derated for use. The INN3378C belongs to the InnoSwitch3 Pro family and adopts PI exclusive PowiGaN technology, which includes GaN gallium nitride power devices. Compared to traditional MOSFETs, it can output higher power.

The main control chip model is INN3365C, also known as the InnoSwitch3-Pro series, which supports 22W wide voltage applications in adapters. Two main control chips are combined with a large and a small transformer to form two independent switching power supplies.

The supporting protocol chip adopts Yingjixin IP2738, which is a dual protocol chip that supports dual port 18-140W fast charging applications, with independent feedback control and USB PD control. It is equivalent to integrating two IP2736 chips into one chip, and the fast charging specifications are the same as IP2736. Supports USB PD3.1 28V EPR gear and rich and comprehensive fast charging protocols such as PD3.0/PPS, with excellent compatibility.
