TPS62933O: Need help confirm schematics

Hi Kevin,

Thanks for reaching to us!

Actually many items in schematic need to be optimized. My comments are listed below.

1. EN-pin max absolute voltage is 6V, cannot pull EN-pin directly to 28Vin.

2. Suggest 0.1uF boot cap, 1nF is too small.

3. Suggest to add a 0.1uF input decoupling cap as close to IC as possible.

4. Only 1uF output cap is not enough. Please refer to datasheet reference schematic and LC recommended table.
