The main controller chip, an SC1933C from PI, is placed between the primary side and the secondary side. It belongs to PI PowiGaN series which is the first GaN-based product launched by PI, marking the full application of GaN components on USB PD fast charging power adapters. Its high frequency and low loss features can improve the power density, reduced size and weight, making it more portable.

IV Conclusion


From the teardown of the RAVPower PD Pioneer 61W GaN Charger, we see the mature of GaN technology. Thanks to the GaN solution from Power Integrations, engineers are now able to reduce a great number of components, and create a 60W charger with ultra-high efficiency that's very similar to a conventional 18W charger, which is unimaginable in early days.


Of course, heat dissipation and EMI has to be taken care of due to the nature of the compact size and GaN component. In this case, Ravpower uses two thermal pads and a dedicated common mode choke to get the job done.


The charging performance is stable with all PD steps including 9V, 12V, 15V, 20V, and an extra 20.3V step. However, it lacks PPS support which would otherwise make it a perfect charger.


First came out at $50, and now constantly discounted at around $40, the Ravpower is very reasonably priced as a cutting-edge charger. We have already seen GaN chargers becoming cheaper in recent times if you follow closely to our GaN charger list, and boy the popularization of GaN chargers has begun.


Pros:

Powerful and compact.

Good components and thoughtful design.

Reasonably priced.


Cons:

Does not support PPS.

$40 at Amazon US
