LP8864S-Q1: Operation of ISEL[10:0]

Koji Hayashi92

Part Number: LP8864S-Q1

Hi TI-team

LP8864S-Q1 has ISEL[10:0] (IDAC).

Does this automatically change the current value ?

How does IDAC(ISEL[10:0]) work ?

Is the reason why there is no ISEL in equations 4,5,6,9,10,11 in the datasheet because it will be 0μA ?

Hi Koji-san,

It changes the output voltage. The Vboost in those equations are changed dynamically based on the value of ISEL.

Hi Charles-san

Thnak you for response.

I understand that the user does not set the bit, but automatically switches inside the IC.
