TPS65910A3A1上电正常,运行一段时候后,电源没有输出,大家有没有遇到这种情况?

Other Parts Discussed in Thread: TPS65910

大家好:

       我用TPS65910A3A1给AM335X供电,上电时电源都正常输出,一段时间后,画面消失了,此时量电压发现,TPS65910A3A1的VRTC是1.8V正常,

PWRHOLD(连接AM335X的PMIC_POWER_EN)电压1.8V正常,但是其他输出电压都没有。大家有没有遇到这种情况 ?  什么原因导致电源管理芯片

正常工作过程中电压突然无法输出?  我的设计用BOOT1:BOOT0 = 10,用EEPROM的上电时序。
