SLVSDG6B May 2016 – April 2021 TPS54302
The TPS54302 incorporates an overvoltage transient protection (OVTP) circuit to minimize output voltage overshoot when recovering from output fault conditions or strong unload transients. The OVTP circuit includes an overvoltage comparator to compare the FB pin voltage and internal thresholds. When the FB pin voltage goes above 108% × Vref, the high-side MOSFET is forced off. When the FB pin voltage falls below 104% × Vref, the high-side MOSFET is enabled again.
