TPS73HD318PWP Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using bypass capacitors to reduce noise and EMI.
  • To ensure stability, it's essential to follow the recommended compensation network and component values provided in the datasheet. Additionally, make sure to use a sufficient output capacitor with a low ESR and a high-quality input capacitor to filter out noise and ripple.
  • While the datasheet specifies a maximum input voltage of 18V, it's recommended to derate the input voltage to 15V to ensure reliable operation and prevent damage to the device. Exceeding the maximum input voltage can cause permanent damage to the device.
  • The output voltage ripple and noise can be calculated using the equations provided in the datasheet. Additionally, you can use simulation tools such as SPICE or PSpice to model the circuit and estimate the output voltage ripple and noise. It's also recommended to use a high-quality output capacitor with a low ESR to minimize output voltage ripple and noise.
  • The thermal derating curve is not explicitly provided in the datasheet, but it can be estimated using the thermal resistance values provided in the datasheet. As a general rule, the device's power dissipation should be derated by 1-2% per degree Celsius above the maximum operating temperature to ensure reliable operation.
