TPS3847108DBVR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS3847108DBVR involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF, and to choose a capacitor with a low ESR (Equivalent Series Resistance). Additionally, the output voltage can be stabilized by adding a small ceramic capacitor (e.g. 100nF) in parallel with the output capacitor.
  • The TPS3847108DBVR can handle a maximum input voltage of 18V. However, it is recommended to operate the device within the recommended input voltage range of 2.7V to 15V for optimal performance and reliability.
  • The output voltage of the TPS3847108DBVR can be programmed using an external resistor divider network connected to the FB (Feedback) pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
  • The TPS3847108DBVR can deliver a maximum output current of 1A. However, the actual output current may be limited by the input voltage, output voltage, and the thermal performance of the device.
