I have a LTM8055 Demo DC2017A, the LTM8055 datasheet shows input can be +5V, but when I add +5V to DC2017A input, the output is only 1.65V; when I rise the input voltage above 5.7V, the output is 12V corrently.
where is the problem? Could anybody help me?
Please make sure that your DC source has enough current to provide at 5VIN. At 6A load at output, input current should be around 14.5A.
thank you for your reply, even connect light load, the output voltage is not correct, the DC source has enough current
