Part Number: TPS65105

Hello,

I'm trying to design using the TPS65105, and I need to have VCOM= 4.04V.I tried so hard to understand how to change VCOM according to the available datasheet. Also I know how to change it through adding a voltage divider by resistances. but is there any other way or any formula that I can use?

Sincerely

Farzaneh

Hello Farzaneh,

VCOM output is just a bufferd version of VCOMIN so I am not sure what you mean by a formula. The easiest way is to just use VO1 and use a resistor divider to generate 4.04V at VIN as shown in the typical application circuit in figure 15 in the datasheet. With the reference designators in that figure, VCOMIN = (R8/(R7+R8)) * VO1.

Kind Regards,

Liaqat
