TPS2491DGSR datasheet by Texas Instruments

TPS2491DGSR Frequently Asked Questions (FAQs)

• What is the maximum current rating of the TPS2491DGSR?
  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.
• How do I ensure the TPS2491DGSR is stable and doesn't oscillate?
  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.
• What is the purpose of the EN pin, and how do I use it?
  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.
• How do I adjust the output voltage of the TPS2491DGSR?
  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.
• What is the minimum input voltage required for the TPS2491DGSR?
  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.
