[参考译文] CC1310：在电磁兼容性(EMC)测试后、直流/直流转换器未在待机模式下工作。

尊敬的 Dmytro：

您能否测试一下如何移除 DCDC_SW 引脚上的电感器并使用内部 LDO 为 VDDR 供电？

在 CCFG 中、需要禁用直流/直流转换器并启用内部 LDO：

#ifndef SET_CCFG_MODE_CONF_DCDC_RECHARGE
// #define SET_CCFG_MODE_CONF_DCDC_RECHARGE 0x0 // Use the DC/DC during recharge in powerdown
#define SET_CCFG_MODE_CONF_DCDC_RECHARGE 0x1 // Do not use the DC/DC during recharge in powerdown
#endif
#ifndef SET_CCFG_MODE_CONF_DCDC_ACTIVE
// #define SET_CCFG_MODE_CONF_DCDC_ACTIVE 0x0 // Use the DC/DC during active mode
#define SET_CCFG_MODE_CONF_DCDC_ACTIVE 0x1 // Do not use the DC/DC during active mode
#endif

我关闭了直流/直流转换器并使用损坏且正常工作的 cc1310进行测试、损坏中的功耗下降到1uA、但 VDDR 仍为零。

Im 抱歉、我移除了错误的电感器、当我移除  DCDC_SW 上的电感器时、 cc1310被唤醒、VDDR 的范围为1、72 - 1、52V、但我们现在想知道为什么直流/直流转换器在本例中不工作、LDO 不是最节能的解决方案。

尊敬的 Dmytro：

启用直流/直流转换器模式后、您可以上传用示波器测得的 VDDR 图像吗？

在测试中、我使用了一个稍作修改的 PIN_STANDBY 示例。

感谢图像、

当箭头标记正确时、器件进入待机状态。

是

尊敬的 Dmytro：

您能再做两次测试吗、休眠持续时间为10ms 和500ms 的测试吗？

两次测试10ms 和500ms SLEEP

我做了另一个使用睡眠时间70ms 的测试、这是设备工作时最长的睡眠时间

尊敬的 Dmytro：

VDDR 总线上有任何其他负载吗？

大家好、Diego、NO
