TPS2012ADR datasheet by Texas Instruments

TPS2012ADR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS2012ADR?
  The maximum input voltage that can be applied to the TPS2012ADR is 12V, but it's recommended to keep it below 10V to ensure reliable operation and to prevent damage to the internal voltage regulator.
• How do I ensure that the TPS2012ADR switches between the two input sources seamlessly?
  To ensure seamless switching, make sure that the input sources are within 100mV of each other and that the input voltage rise and fall times are slower than 10μs. Additionally, use a low-ESR capacitor on the output to minimize voltage droop during switching.
• What is the minimum input voltage required for the TPS2012ADR to operate?
  The minimum input voltage required for the TPS2012ADR to operate is 2.7V, but it's recommended to keep it above 3V to ensure reliable operation and to prevent brownout reset.
• Can I use the TPS2012ADR as a high-side switch?
  No, the TPS2012ADR is designed as a low-side switch, and it's not recommended to use it as a high-side switch. Using it as a high-side switch may cause damage to the device or affect its reliability.
• How do I calculate the power dissipation of the TPS2012ADR?
  The power dissipation of the TPS2012ADR can be calculated using the formula: Pd = (VIN - VOUT) x IOUT. Make sure to consider the maximum junction temperature and thermal resistance when calculating the power dissipation.
