TPS65266RHBT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65266RHBT involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. It's also recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • The input capacitor should have a low ESR and be rated for the maximum input voltage. A 10uF to 22uF ceramic capacitor is a good starting point. The output capacitor should be chosen based on the output voltage and current requirements, and should have a low ESR and a high ripple current rating.
  • The TPS65266RHBT is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the thermal design. It's recommended to follow the thermal design guidelines in the datasheet to ensure reliable operation.
  • The TPS65266RHBT output voltage is set using the FB pin and an external resistor divider network. The datasheet provides a formula to calculate the required resistor values for a specific output voltage. It's recommended to use a 1% or better tolerance resistor to ensure accurate output voltage regulation.
  • The TPS65266RHBT is capable of delivering up to 3A of output current, but the maximum output current depends on the input voltage, output voltage, and thermal design. It's recommended to follow the power dissipation and thermal design guidelines in the datasheet to ensure reliable operation.
