GaN Charger ICs & OEM Charger Sourcing from China
1 resources tagged with "Charger"
GaN (gallium nitride) charger ICs let factories build smaller, cooler, higher-power USB-C chargers, and the silicon comes mainly from Navitas, Innoscience, and Power Integrations. A current OEM GaN charger targets USB PD 3.1 EPR (up to 28V/140W or higher) and must meet UL 62368-1 for safety, with the GaN switch and controller driving most of the BOM cost. The sourcing risk is authenticity — counterfeit or downgraded GaN ICs that overheat — plus verifying the real PD output profile against the label.
Sourcing GaN chargers means checking the actual GaN IC and PD controller part numbers, since the power and efficiency claims hinge on them. The common pitfall is a charger labeled '140W' that throttles under load because of an undersized GaN switch or a relabeled IC — we decap or bench-test power delivery to confirm.

FAQ
How do I verify a GaN charger's real power output?
Bench-test the USB PD profiles with an electronic load and a PD analyzer, checking sustained (not peak) output and temperature. Confirm the GaN IC and PD controller part numbers on the BOM match named vendors like Navitas or Innoscience.
What safety certification do GaN chargers need?
UL 62368-1 for the US and IEC/EN 62368-1 for the EU, plus DOE Level VI efficiency for US sale. For multi-market launches you may also need UKCA and Japan PSE.
