TPS70148PWP Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS70148PWP involves placing the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a separate analog and digital ground plane to reduce noise coupling.
  • To ensure stability, it's essential to follow the recommended component values and PCB layout guidelines. Additionally, the output capacitor should be selected based on the output voltage and current requirements. A minimum of 10uF output capacitance is recommended, and the ESR of the capacitor should be less than 1 ohm.
  • The TPS70148PWP can handle a maximum input voltage of 18V. However, it's recommended to operate the device within the specified input voltage range of 5.5V to 15V for optimal performance and reliability.
  • The TPS70148PWP is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve provided in the datasheet.
  • The output voltage of the TPS70148PWP can be calculated using the following formula: Vout = (R1/R2) * (Vref), where R1 and R2 are the resistors connected to the FB pin, and Vref is the internal reference voltage (1.22V).
