Hello:
We had a design using TPS65150, Vin=3.3V, and three Vouts(AVDD=11V; VGH=18V; VGL=-6.8V).
Now we have a new project: Vin=12V, Vouts(AVDD=9.8V; VGH=18V; VGL=-6.5V).
The datasheet says: Vin range is 1.8V-6V. I have to stepdown Vin 12V to <6V. I may use 5.8V
Vouts can be adjusted by trimming the resistors.
Compared to old design, Vin is changed, should the switching choke, diode, input/output caps need changed too? and how about other parameters such as comp RC ?
I attached the old design schematic, power supply is on Page2 on TI technical support request (Case CS1268976). Would you please give us some suggestions?
Thanks.
