TPS2490DGSRG4 datasheet by Texas Instruments

TPS2490DGSRG4 Frequently Asked Questions (FAQs)

• What is the maximum current rating of the TPS2490DGSRG4?
  The maximum current rating of the TPS2490DGSRG4 is 2A, but it can be limited by the thermal performance of the PCB and the ambient temperature.
• How do I ensure the TPS2490DGSRG4 is stable and doesn't oscillate?
  To ensure stability, it's essential to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 10nF-100nF ceramic capacitor between the FB pin and GND.
• 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 or 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 TPS2490DGSRG4?
  The output voltage can be adjusted by using a resistive divider network between the output and the FB pin. The ratio of the resistors determines the output voltage.
• What is the minimum input voltage required for the TPS2490DGSRG4?
  The minimum input voltage required for the TPS2490DGSRG4 is 2.7V, but it's recommended to use a minimum of 3V to ensure proper operation.
