BQ24074: Efficiency of BQ24074?

Peter Naylor
Prodigy 60 points
Part Number: BQ24074

Hi,

I would like to know the efficiency of the BQ24074 over a range of input voltages/currents, e.g. 4.35V - 10.3V and 0A - 1.5A.  I do not see any efficiency data in the datasheet... Is it available elsewhere?

Thank you,

Peter

    Hello
    The bq24074 is linear charger with low operating current and efficiency is going to be similar to an LDO. With low operating current the output current is appropriately the input current and efficiency is then Vout/Vin. The closer Vin is to Vout the higher the efficiency and lower power dissipation on the device.
