Questions for your ADP5080

Dear Sir/Madam,

We are just studying your ADP5080.

So I have some questions for you.

1)Do you have the trace layout of evalboard?

  We would like to use for our reference design.

2)If we dont use ch-7, then how should we deal any setting?

3)If we dont use your charge pump, then how should we deal any setting?

Thanks, Kaos

    Hello and thank you for your interest in ADI power.

    I can send you the eval board gerber files for reference.

    Please send me an email at allan.fisher@analog.com so that I have your address.

    Channel 7 is off by default, and can be turned on using I2C control.

    If you are not using ch7, connect the channel 7 input to the input voltage and leave the ch.7 output pin open.

    The charge pump is used to provide the drive voltage to the internal power fets for channels 1-6.

    The charge pump output is typically routed to the BST pins: BST16, BST45, and BST23

    If it is not used, you will have to provide a 5V supply, floating on the input voltage to these pins.

    The charge pump itself cannot be turned off and has undervoltage detection, so the schematic around the charge pump should be followed.

    I highly recommend using the charge pump.

    Please let us know if you have any further questions.

    Regards,

    Allan
