🔌 The Apple USB-C Dongle is hardware-limited to 0.5V on Android devices without special third-party apps. The CX31993 has no such restriction. It will natively push its full 1V power on Android, Windows, and Mac, giving your In-Ear Monitors (IEMs) the juice they actually need.
Ensure the dongle is not trapped under a phone case or in a tight pocket while in use. Allowing airflow around the metal chassis can significantly reduce surface temperature. Conclusion: Is the Heat a Problem?
If you are designing a custom PCB or modifying a commercial dongle (like the Abigail, JCALLY, or Syntech variants), hardware-level thermal management is the most effective solution. Thermal Pad and Copper Pour Upgrades cx31993 datasheet fix hot
From analysis of well-behaved CX31993 designs (e.g., certain JCALLY, Avani dongles), the following layout fixes are effective:
