TPS79501DCQR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS79501DCQR involves placing the input and output capacitors close to the device, using a solid ground plane, and keeping the input and output traces separate to minimize noise coupling. TI provides a recommended PCB layout in the datasheet and application notes.
  • To ensure stability, make sure to follow the recommended output capacitor selection and ESR values, and use a minimum output capacitance of 10uF. Additionally, ensure the input voltage is within the recommended range, and the device is operated within the specified temperature range.
  • The TPS79501DCQR can handle a maximum input voltage of 5.5V, but it's recommended to operate within the specified input voltage range of 2.2V to 5.5V for optimal performance and reliability.
  • The TPS79501DCQR is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and ensure proper thermal management to ensure reliable operation.
  • The output voltage of the TPS79501DCQR is adjustable using the FB pin and an external resistor divider network. The output voltage can be calculated using the formula: Vout = 0.6V x (R1/R2 + 1), where R1 and R2 are the resistors in the divider network.
