Part Number: TPS54560 tps54560.pdf 您好,我在立创商城看到的这款芯片,按照第24页推荐电路搭建好之后,不能正常输出5v。这个电路中我通过焊接R10或R11或R12来输出3.3v/5v/12v,但是都失败了,测FB脚电压也不是0.9v。然后我改变输入电压,输出电压也会跟着变化。

I have the following questions
1. The manual of TPS61222 states that the ISW switch current is limited to 200mA. Does it mean that 200mA is required to make the chip work properly? The results of my tests seem to require that the input current be greater…
