TPS51518RUKT Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS51518RUKT datasheet (section 10.2) and in the application note SLVAE04. It's essential to follow these guidelines to minimize noise, ensure proper thermal management, and optimize performance.
  • The selection of input and output capacitors depends on the specific application requirements. TI recommends using low-ESR capacitors with a minimum capacitance of 10uF for the input and 22uF for the output. The capacitor selection guide in the datasheet (section 7.3.1) provides more information.
  • The TPS51518RUKT is rated for operation up to 105°C ambient temperature. However, it's essential to consider the thermal design and ensure proper heat dissipation to maintain reliable operation.
  • The output voltage can be configured using the FB pin and an external resistor divider network. The datasheet (section 7.3.2) provides a formula to calculate the required resistor values for a specific output voltage.
  • The minimum input voltage required for proper operation is 2.7V. However, it's recommended to ensure a minimum input voltage of 3V to account for voltage drops and ensure reliable operation.
