BQ25892: bq25892 / Efficiency data at 0degC and 45degC

Part Number: BQ25892


Hi,

I understand that the efficiency data in datasheet was measured under room temp, then do you have any actual data with other temperature? The customer would like to know how does it vary over temperature. Any temperature will be helpful but their planning temperature range is from 0 degC to 45 degC.

Best Regards,

    Satoshi-san,

    We do not have efficiency data over temperature. Most of difference will be conduction losses from the FETs and inductor DCR. Estimation is relatively straight forward. If you need help, we can go off line for discussion.
