TPS54J061: Papice for TI的仿真,搭建电路后无输出

Part Number: TPS54J061


搭建TPS54J061的仿真电路后,可以正常仿真无报错,但是输出电压为0

...

        很可能是模式问题,建议你采用在线仿真webench.

  • 这是整个电路的一部分,最终不是为了只仿真这部分。

    发现昨天的电路没有电感,添加了电感重新做仿真。参数按照application重新做了修改,出现了如下报错:

    ERROR(ORPSIM-15138): Convergence problem in Transient Analysis at Time = 10.00E-12.

  • 另外,模式问题指什么?

  • option修改为auto  converge后,不报错。但是仍然没有输出

       模型问题。 (写错成模式)
