9 Power Supply Recommendations

The TPS65053-Q1 has only a few power supply recommendations in addition to adhering to the minimum and maximum values in the Recommended Operating Conditions. The following check list provides power supply recommendations that should be used in conjunction with complying to the Recommended Operating Conditions of the device.

  • 1-µF Bypass cap 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, and VIN_LDO2/3 supplies if used.
  • Output filters must be used on the outputs of the DCDC converters if used.
  • Output capacitors must be used on the outputs of the LDOs if used.
