9 Power Supply Recommendations

The TPS53311 device is designed to operate from an input voltage supply range from 2.9 V to 6 V (2.9 V to
3.5 V biased). This input supply must be well regulated. Proper bypassing of input supplies and internal regulators is also critical for noise performance, as is PCB layout and grounding scheme. See the recommendations in Layout.
