TPS51218: VFB voltage at CCM condition

Part Number: TPS51218

Hello,

Our customer asked VFB voltage min, max value at CCM condition, ever since he could see these number in Skip mode but could not see in CCM in the datasheet.

Best regards,

  • Hi Imi-san,

    In datasheet, it marked as (1) which means this data is  ensured by design. Not production tested. We don't have the min and max value of VFB at CCM condition. 

    You can refer to Skip mode. They are familiar or CCM is a little bit smaller than Skip mode.

    Thanks,

    Lishuang

  • Thank you for your reply.

    I understood Vref tolerance in CCM is similar or slightly lower to Skip mode, that is 0.7000V +/-0.5% @Ta=25C, 0.7000V +/-0.8% @Ta=0C to 85C, 0.7000V +/-1.0% @Ta=-40C to 85C.

    best regards,
