Hi team,

Customer would like to know efficiency when VCC is 12~17V.

Could you provide please?

(We can see the case of VCC=25V in datasheet p29)

Best regards,

Goto

Hi Goto,

I do not have any efficiency data for the 650 at those input voltage values. However, the BQ24610 sister device datasheet has efficiency plots at 12V and 20V on page 13.

Hi Jeff,

Thank you for kind support.

Can I regard 650 and 610 as same efficiency?

Hi Goto,

If their respective EVMs have the same or very similar inductor DCR and external FET Rdson, then yes.
