TPS2490DGS datasheet by Texas Instruments

TPS2490DGS Frequently Asked Questions (FAQs)

• What is the maximum current rating of the TPS2490DGS?
  The maximum current rating of the TPS2490DGS is 2A, but it can be limited by the thermal performance of the PCB and the ambient temperature.
• How do I ensure the TPS2490DGS is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and add a 10nF-100nF ceramic capacitor between the FB and VOUT pins.
• 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, and connect EN 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 TPS2490DGS?
  The output voltage can be adjusted by using a resistive divider network between the FB pin and the output voltage. The ratio of the resistors determines the output voltage.
• What is the minimum input voltage required for the TPS2490DGS?
  The minimum input voltage required for the TPS2490DGS is 2.7V, but it's recommended to use a minimum input voltage of 3V for optimal performance.
