Hello,
Regarding the TPS2592AA device:
The Evaluation module user’s guide has D5 in the schematic connected to BFET & OUT pins.
This is not shown in the datasheet examples.
Could you please explain what D5 is being used for?
Thank you, Keith

Hi Keith,
D5 is used with blocking FETS (Q3) that have a smaller negative Vgs (abs max) than the output voltage. On the EVM, Q3 Vgs = +16V / -12V and D5 clamps the negative Vgs to a safe value. A blocking FET with Vgs = +/- 20V would not need D5.
I should have mentioned this in the EVM user guide.
