This chapter provides additional information about the TPS54x80EVM-228.
If the core and I/O voltages are provided by the two dc/dc regulators running
at a slightly different frequencies with the same input power supply, their input
voltage ripple always includes a low frequency harmonic. Usually this effect
is called the
beating
frequency. The input voltage ripple (Channel 2) of two
nonsynchronized regulators running at frequencies about 15% apart is shown
in Figure A-1.
