LP8860-Q1: Question of ILED equation

Part Number: LP8860-Q1

Hi team,

Can you review the followin ILED equation of LP8860-Q1?

For DRV_EN_EXT_LED_CUR_CTRL = 0, ILED formula is as follows.

  

    DISP_CL1_CURRENT = 1023

    DRV_LED_CURRENT_SCALE = 80mA

    DRV_OUTx_CORR = 0 %

When using above configuration, the ILED is calculated as below. 

     ILED = 1023 / 4095 x 80 x (0+100) / 100 = 19.985

     -> Is this correct?

     -> What is the unit (mA or A)?

Thanks,

Sam Lee
