TPS65252RHDT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65252RHDT 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 output voltage of the TPS65252RHDT can be set using the FB pin. The recommended output voltage range is 0.9V to 3.3V. Choose an output voltage that meets the requirements of your load, taking into account the voltage drop across the output capacitor and the maximum current rating of the device.
  • The TPS65252RHDT can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
  • To ensure the stability of the output voltage, use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a high ripple current rating. The recommended output capacitor value is 10uF to 22uF. Also, make sure the output voltage is within the recommended range and the input voltage is stable.
  • The TPS65252RHDT can deliver up to 2A of output current, but the maximum output current depends on the input voltage, output voltage, and ambient temperature. It's recommended to derate the output current at high temperatures and high input voltages.
