TPS65253RHDR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65253RHDR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • The output voltage of the TPS65253RHDR can be set using the VID pins. The recommended approach is to use a resistive divider network to set the output voltage. The datasheet provides a formula to calculate the required resistor values based on the desired output voltage.
  • The TPS65253RHDR can handle input voltages up to 25V, but it's recommended to operate within the specified range of 6.5V to 18V for optimal performance and reliability.
  • To ensure stability and reliability, it's essential to follow the recommended layout guidelines, use the correct output capacitors, and ensure that the input voltage is within the specified range. Additionally, it's recommended to add input and output filtering to reduce noise and ripple.
  • The TPS65253RHDR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliability and prevent overheating.
