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。

Hi
见datasheet描述:
The device will terminate charging when the termination current threshold has been reached and will begin a recharge cycle when the battery voltage has dropped below the recharge threshold (VRECHG).
当充电电流小于the termination current…
