关于TPS65218上电没有输出

Other Parts Discussed in Thread: AM4377, TPS65218

TI技术支持,您好!

问题:使用TPS65218给AM4377进行供电管理,

已满足如下4个条件:1、pin9 AC_DET上拉至VCC5V;2、pin44 PB上拉至VCC5V,且通过跳线帽可连接到GND;3、pin46 PWR_EN上拉至VCC5V;4、IN_BU,IN_BIAS,IN_LDO1,IN_DCDC3,IN_DCDC4,IN_DCDC1,IN_DCDC2,IN_LS2,IN_LS3,均已提供VCC5V的输入;

但是TPS65218没有输出。

请问还需要提供什么条件?
