TPS40195PWR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS40195PWR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. TI provides a recommended layout in the datasheet and in application notes.
  • Choose input capacitors with a voltage rating higher than the maximum input voltage, a capacitance value between 4.7uF to 10uF, and an ESR (Equivalent Series Resistance) less than 100mΩ. X5R or X7R ceramic capacitors are good options.
  • The maximum output current of the TPS40195PWR is 1.5A. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations. Always check the power dissipation and thermal calculations to ensure reliable operation.
  • The output voltage of the TPS40195PWR can be adjusted by using a resistor divider network between the VOUT pin and the GND pin. The datasheet provides a formula to calculate the required resistor values for a desired output voltage.
  • The EN (Enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. This pin can be used to implement power sequencing or to turn off the regulator when not in use.
