TPS3840DL32DBVRQ1 Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS3840 application note (SLVAE04) which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The output voltage setting resistors (R1 and R2) can be calculated using the formula provided in the datasheet. Additionally, Texas Instruments provides a voltage setting resistor calculator tool on their website to simplify the process.
  • Although the datasheet specifies a maximum input voltage of 6V, it's recommended to limit the input voltage to 5.5V to ensure reliable operation and prevent damage to the device.
  • The TPS3840 has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold can be set by selecting the appropriate resistor values for the divider network.
  • The DELAY pin is used to delay the power-good signal (PG) output. This can be useful in systems where the power supply requires a delay before the PG signal is asserted. The delay time can be set by connecting a capacitor and resistor to the DELAY pin.
