请问CC1310片内DC/DC转换器可以关闭吗?

请问,CC1310片内DC-DC转换器输出的电压电流参数在哪可以查到,片内DC/DC转换器可以关闭吗?芯片进入休眠或SHUTDOWN后,DCDC_SW的输出是什么状况?

您可以参考http://www.ti.com.cn/cn/lit/ug/swcu117f/swcu117f.pdf 
The DC-DC converter is controlled through the AON_SYSCTL:PWRCTL register.
To enable the DC-DC converter when the system is active, the AON_SYSCTL:PWRCTL.DCDC_ACTIVE bit must be set.

疑问已解决,最想知道的关键问题在手册上已经有了答复:
NOTE: The DCDC regulator output cannot be used to supply external circuitry.
