Hi,

I received a following question from my customer.

Do you have the plan to prepare the calculation tool ?

Best Regards,

    Hi,

    It seems that customer question part is not included in this.

    Could you include it or be more specific for calculation tool?

    Thanks,

    Yoon-san,

    Thank you for your help and I apologize lack of information.

    The calculater requested from my customer is used to design external part such as following file;

    Could you confirm it?

    Best Regards,

    Hi Kuramochi-san,

    I will check with the original design/apps team for this and get back to you.

    Thanks,

    Hi Kuramochi-san,

    Unfortunately, calculation tool is not available for LP8860-Q1.

    This is the answer from the original project team.

    We do not have similar excel.

    This is what we have been using instead:

     As part of EVM GUI package there are two EEPROM files (.eep) for boost Fsw=300kHz and Fsw=2.2MHz.

    LP8860 does not have external compensation components, boost parameters are in EEPROM

    • Power Stage Designer can be used for estimating application currents & voltages, for external component ratings

    • If customer wants to use external components that are significantly different than in DS application examples, boost stability (PM) can be measured using EVM

     I'm so sorry for not providing what you exactly wanted, but hope this would be a little help for you.
