Part Number: TPS65105

Hello Team,

Could you recommend me with the schematics for TPS5105 for the following output requirements with input power supply of 3.3V:

AVDD-9.6V

VGH-18V

VGL- -6V

VCOM-3V

And also I would like to know the Power On Sequence of the following voltages.

Thank you and regards,

Hello Nishmitha,

Please have a look on page 24 in the datasheet of TPS65105. The schematic there is very similar to your requirements. You only need to recalculate R1, R3. R5 and R7 according the above voltages.
Please use formulas 7, 8, 9, 11, and for VCOM as well the resistor divider calculation with a reference of 3V.

Best regards,
Brigitte
