TPS2491DGSR Frequently Asked Questions (FAQs)

  • The maximum current rating of the TPS2491DGSR is 2A, but it can be limited by the thermal performance of the PCB and the ambient temperature.
  • To ensure stability, follow the layout guidelines in the datasheet, use a low-ESR capacitor for Cout, and add a 10nF-100nF capacitor in parallel with Rset to filter noise.
  • The EN (enable) pin is used to turn the device on and off. Connect EN to VIN to enable the device, or connect it to GND to disable it. You can also use a logic signal to control the EN pin.
  • The output voltage can be adjusted by changing the resistor divider ratio of R1 and R2. Use the formula in the datasheet to calculate the desired resistor values.
  • The minimum input voltage required for the TPS2491DGSR is 2.7V, but it's recommended to use a minimum of 3V to ensure proper operation.
