您好,
TSW1400EVM版本是D版本还是E版本?如果是D版本的话,需要去掉R55电阻,请确认下这一点;
另外,也请确认下5V供电电源可以至少提供3A的电流;
确认以上2点后如果还是异常,通过下面3个E2E英文帖子的回复,很可能是板子有问题,建议您参阅下面这个链接:https://www.ti.com.cn/zh-cn/support-quality/additional-information/customer-returns.html
建议您去掉R55试试,且保证5V供电电源可以至少提供3A的电流;
本来 DAC3162EVM 可以配合 TSW3100 板进行测试的,但是TSW3100 板已经停产了,DAC3162EVM 现在只能使用TSW1400EVM了;
