Part Number: LP8860-Q1

Please let us know IOUT Output current accuracy (@IOUT = 85 mA)

We only find accuracy at IOUT=150 mA    Min:−3% Max:3%

    Hi Kurahara-san,

    LED current accuracy of LP8860 is trimmed at 150mA and error will be increased by lowering current values.

    In general, error range of LED current will increase 2~3 times when current value is reduced to <10% from its max value.

    So, estimated accuracy number at 85mA will be ~+/-5% though actual accuracy can be much better.

    But TI doesn't guarantee LED current accuracy at other than 150mA.

    If you are supporting Panasonic, I'm getting same inquiry from Yuki-san. Please discuss with him for more detail info on this.

    Otherwise, please send me an email for more info.

    Hope this helps,

    Sungho
