### 供电

Radxa CM5 模块输入电压（VCC_SYSIN）范围为 3.6V-5.2V，在 4V 时效率最高。若输入电压达到或超过 5V，电压调节电路可能产生可闻的嗡鸣声。

典型工作电流为 2A。设计载板供电电路时，推荐使用 4V 3A 电源。

:::note
Rockchip 官方推荐为 RK806 PMU 提供 4V 电源，以确保最佳效率和峰值性能。使用 5V 电源可能降低效率，并可能导致 DC-DC 啸叫问题。

### Power Supply

The input voltage range of the Radxa CM5 module (VCC_SYSIN) is 3.6V-5.2V, with the maximum efficiency achieved at 4V. Supplying 5V or above may cause audible humming from the voltage regulating circuit.

Typical current consumption is 2A. For the power supply circuit on your carrier board, we recommend a 4V 3A supply.

:::note
Rockchip officially recommends a 4V power supply for the RK806 PMU to ensure optimal efficiency and peak performance. Using a 5V supply may result in reduced efficiency and potentially lead to DC-DC whistling issues.
