9 Power Supply Recommendations

In addition to the values listed in the Recommended Operating Conditions table, additional recommendations for the power supply are as follows:

  • 1-μF bypass capacitor on VCC, located as close as possible to the VCC pin to ground.
  • VCC and VINDCDC1/2 must be connected to the same voltage supply with minimal voltage difference.
  • Input capacitors must be present on the VINDCDC1/2, VIN_LDO1, VINLDO2, and VIN_LDO3/4 supplies if used.
  • Output inductor and capacitors must be used on the outputs of the DC-DC converters if used.
  • Output capacitors must be used on the outputs of the LDOs if used.
