I have a question on output discharge of TPS53515.

Is it using internal discharge resistor or Low FET ON while High FET OFF.

Or does the IC return the output charges to the input side?

Hi，

It will turn on the low-side FET beyond the zero inductor current quickly discharges the output capacitor.
