    in reply to: DROK 090089 Boost Converter Help? #10965

    Hello Dave Hallidy,
    Thank you for writing in.
    According to your description, the input power in your application is 13.8V*20A=276W and the output power is 28V*10A=280W.
    The output power is higher than the input power which caused the modules cannot output enough current for your need.
    Could you please try to use an other power supply with larger power and the output current of each unit should be adjusted to 5.5A to see if they can work for your need?
    Hope this can help you.
    Best regards
