BQ24133: Input Current and Output Current

Part Number: BQ24133

Dear Sir, Madam,

Can I check if the input for BQ24133 is 12V/1A, is the output current possible to be higher than 1A?

Thanks.

  • Hi Hong,

    Because it is a buck converter, you can expect more than 1A on the output. For the exact amount, you can use the following formula:

    IOUT = (Efficiency*VIN*IIN)/(100*VOUT), where VIN = 12V, IIN = 1A, VOUT = VBAT, and Efficiency is figure 21 of datasheet.

    Regards,
    Steven
