TPS568231: schematic review of TPS568231

Hi Jimmy,

After reviewing the schematics, my comments are below:

• For both schems: Please ensure that after the derating of the output capacitors, the value is within the Min and Max Cout values in Table 8-2 in the datasheet on page 21. I would highly recommend following the 3.3Vout recommended component values and the 0.6Vout component values for your 0.8Vout schematic.
• For both schems: Same for the input capacitors, please ensure they are above 40uF capacitance after derating.

Other than this, the schematics look good.

You can follow the Application and Implementation section in the datasheet for extra design guidance.
