TPS2104DBVT datasheet by Texas Instruments

TPS2104DBVT Frequently Asked Questions (FAQs)

• What is the maximum current that can be drawn from the output of the TPS2104DBVT?
  The maximum current that can be drawn from the output of the TPS2104DBVT is 1.2A, but it's recommended to limit the output current to 1A for reliable operation.
• How do I ensure the TPS2104DBVT switches between the two input sources seamlessly?
  To ensure seamless switching, make sure the input sources are within 100mV of each other, and the output capacitor is properly sized to minimize voltage droop during switching.
• 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. When EN is high, the device is enabled, and when EN is low, the device is disabled and the output is disconnected from both input sources.
• How do I handle inrush current when using the TPS2104DBVT?
  To handle inrush current, use a soft-start circuit or a current-limiting resistor in series with the output to limit the inrush current during startup.
• Can I use the TPS2104DBVT with input sources that have different voltage levels?
  Yes, the TPS2104DBVT can handle input sources with different voltage levels, but the difference should not exceed 1.5V. If the voltage difference is greater, use external voltage regulators or level shifters to ensure proper operation.
