TPS65268QRHBRQ1 Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS65268QRHBRQ1 datasheet, which includes guidelines for component placement, routing, and thermal management. Additionally, the TI website offers a PCB layout guide and a layout checklist to help designers optimize their board design.
  • The selection of the output capacitor depends on the specific application requirements, such as output voltage, current, and ripple. TI recommends using a low-ESR capacitor with a minimum capacitance of 10uF and a maximum ESR of 100mΩ. The datasheet provides a detailed guide for selecting the correct output capacitor.
  • The TPS65268QRHBRQ1 has an absolute maximum input voltage rating of 18V. However, the recommended operating input voltage range is 6.5V to 14V. Exceeding the absolute maximum rating can damage the device.
  • The TPS65268QRHBRQ1 has a resistive divider network that sets the output voltage. The datasheet provides a formula to calculate the required resistor values for a specific output voltage. TI also offers a voltage calculator tool on their website to simplify the process.
  • The thermal derating curve for the TPS65268QRHBRQ1 is provided in the datasheet, which shows the maximum allowed power dissipation versus ambient temperature. The curve helps designers to determine the maximum output current and power dissipation at a given temperature.
