TPS543C20RVFT Frequently Asked Questions (FAQ)

  • The recommended PCB layout for the TPS543C20RVFT is to keep the inductor and capacitor close to the IC, and to use a ground plane to reduce noise and improve EMI performance. It's also recommended to use a decoupling capacitor between the input and output to reduce noise and improve stability.

  • The TPS543C20RVFT has an internal overcurrent protection circuit that will shut down the IC if the current exceeds 2.5A. The IC will automatically restart once the current drops below 1.5A.

  • Yes, the TPS543C20RVFT can be used in high-frequency switching applications, but it's recommended to use a high-frequency compensation network to ensure stability and prevent oscillations.

  • The TPS543C20RVFT has a built-in input voltage transient suppression circuit that can handle input voltage transients up to 20V. However, it's recommended to use a transient voltage suppressor (TVS) diode in parallel with the input capacitor to further improve transient immunity.

  • Yes, the TPS543C20RVFT is designed to operate in high-temperature applications up to 150°C. However, it's recommended to derate the IC's current and voltage ratings at high temperatures to ensure reliable operation.
