TPS65171RHAR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65171RHAR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • Choose input capacitors with a voltage rating of at least 1.5 times the maximum input voltage, and an ESR of less than 1 ohm. For output capacitors, choose ones with a voltage rating of at least 1.5 times the output voltage, and an ESR of less than 0.1 ohm. X5R or X7R ceramic capacitors are recommended.
  • The TPS65171RHAR can operate in an ambient temperature range of -40°C to 85°C. However, the device's junction temperature should not exceed 125°C.
  • The power dissipation of the TPS65171RHAR can be calculated using the formula: Pd = (VIN x IIN) - (VOUT x IOUT). The thermal resistance of the package (θJA) is 24.4°C/W, and the maximum power dissipation is 2.5W.
  • The EN (enable) pin is used to turn the device on or off. When the EN pin is high, the device is enabled, and when it is low, the device is disabled. The EN pin can be connected to a logic signal or a push-button switch.
