1, LM25143 chip configuration for dual output, one of the way PGOOD abnormal will affect the output of the other way!(LM25143芯片配置为双路输出时,其中一路PGOOD异常是否会影响另一路的输出)
2、Please provide the LM25143simplis model and LTspice model.(请提供一下LM25143simplis模型和LTspice模型)
HI
芯片具有独立的使能和 PGOOD 功能,所以一路异常不影响另外一路。
TI芯片官网没有提供的模型我们也是没有的,建议你借助webench : webench.ti.com/.../switching-regulator 输入芯片名称进入。
