TPS65235-3RUKR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65235-3RUKR 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 capacitors should be chosen based on the output voltage and current requirements. A general rule of thumb is to use ceramic capacitors with a capacitance value of 10uF to 22uF and a voltage rating of 1.5 to 2 times the output voltage. The ESR (Equivalent Series Resistance) of the capacitor should be low, typically less than 10mΩ.
  • The TPS65235-3RUKR 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.
  • The output voltage of the TPS65235-3RUKR can be adjusted by using a resistor divider network between the FB pin and the output voltage. The resistor values can be calculated using the formula provided in the datasheet.
  • The thermal derating curve for the TPS65235-3RUKR is provided in the datasheet. It shows the maximum output current that the device can handle at different ambient temperatures. The curve is based on a junction temperature of 150°C and a maximum operating temperature of 125°C.
