Hi Grady,

Q1) Is the Inductor selection and Diode selection correct?

[Patrick] what are the output current of the 4 output rails? I need to calculate the inductor peak current.

Q2) Are there any other errors or modifications in the setup circuit?

[Patrick] The schematic looks good.

Q3) Are the capacitances of the input/output caps correct?

[Patrick] They look good.

Q4) Does it meet the design criteria guided by TI?

[Patrick] Yes.

Q5) Is there a calculation tool sheet available?

[Patrick] Sorry we don't have such tool for this device.

The output currents for the four output rails are as follows, based on the attached image:

• VGH (13.54V): 30mA
• VGL (-8.49V): 30mA
• VSP (6.7V): 70mA
• VSN (-6.7V): 70mA

Please review the inductor and diode again.
