2.8 Frequency Spread Spectrum

Some parts (like TPS62933x) supports frequency spread spectrum, which helps with lowering down EMI noise. The purpose of spread spectrum is to eliminate peak emissions at specific frequencies by spreading emissions across a wider range of frequencies than a part with fixed frequency operation.
