HI Sir

May Spec is

Vout = 12V

Vout = +/- 16V

Iout+ = 1A

Iout- = 1A

Use TPS54360

Could you help me to confirm the resistor and cap value is correct ?

Thanks

First off it looks like you are exceeding the maximum combined output current for V+ and V- of 1.569 A. You are trying to draw 1 +1 = 2A.

HI John

Sorry I don't see the excel file have 1.569A this value ,May I know where the 1.569A come from ?
My Spec need to do Vout+ = 16Vout/1A and Vout- = -16Vout/1A ,do you have any suggestion of TPS54360 ?

Thanks

Kai,

Look in cell C63 to see the maximum available output current of 1.569 A. You may want to consider TPS54560 for this application, however the calculator does not presently support it.
