TPS51916RUKR Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for optimal performance. TI recommends a 4-layer PCB with a solid ground plane, and to keep the input and output capacitors close to the device. Also, keep the high-current paths short and wide to minimize resistance and inductance.
  • Choose input capacitors with low ESR and high ripple current rating. For output capacitors, choose ones with low ESR and high capacitance. The datasheet recommends a minimum of 10uF for the input capacitor and 22uF for the output capacitor.
  • The TPS51916RUKR is rated for operation up to 85°C ambient temperature. However, it's recommended to derate the output current at higher temperatures to ensure reliable operation.
  • To ensure stability, follow the datasheet's guidelines for component selection and PCB layout. Also, make sure to add a compensation capacitor (CC) between the COMP and GND pins, and adjust its value based on the output voltage and capacitance.
  • The TPS51916RUKR is rated for up to 1.5A output current. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations. Always check the device's thermal performance and adjust the output current accordingly.
