TPS53317RGBT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS53317RGBT involves placing the input capacitors close to the VIN pin, and the output capacitors close to the VOUT pin. The inductor should be placed close to the SW pin, and the diode should be placed close to the SW pin as well. A solid ground plane is also recommended to reduce EMI.
  • When choosing an inductor for the TPS53317RGBT, consider the inductor's saturation current, DC resistance, and self-resonant frequency. The inductor should be able to handle the peak current of the converter, and its DC resistance should be low to minimize power loss. A good starting point is to use an inductor with an inductance value between 1uH and 4.7uH.
  • The maximum input voltage for the TPS53317RGBT is 5.5V. Exceeding this voltage may damage the device.
  • The output voltage of the TPS53317RGBT can be adjusted by changing the resistor divider network connected to the FB pin. The output voltage is determined by the ratio of the resistors, and can be calculated using the formula: VOUT = 0.6V x (R1 + R2) / R2.
  • The maximum output current of the TPS53317RGBT is 3A. Exceeding this current may cause the device to overheat or malfunction.
