TPS65105: Voltage Double mode or triple mode

RSV

Prodigy 165 points

Part Number: TPS65105

Hi,

We are using TPS65105PWP for our design. I am currently generating following voltages listed below.

For both requirement 1 and requirement 2 i am using doubler mode. Is it correct or do i need to change tripler mode??

Requirement 1:

VO1=11.11V

VO2=-6.81V

VO3=19.98V

VO4=3.3V

VCOM=4.2V

Requirement 2:

VO1=9.57V

VO2=-6.04V

VO3=17.86V

VO4=3.3V

VCOM=4.2V

Hello Sakthivel,

Based on the boost output voltage to positive charge pump output voltage guidance in the datasheet, I would recommend to use the tippler mode for your application.
Kind Regards,
