TPS2212IDB datasheet by Texas Instruments

TPS2212IDB Frequently Asked Questions (FAQs)

• What is the maximum current that can be drawn from the TPS2212IDB?
  The maximum current that can be drawn from the TPS2212IDB is 2A, but it's recommended to limit the current to 1.5A for reliable operation.
• How do I ensure the TPS2212IDB 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 handle the transition.
• 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 it to a logic high (VCC) to enable the device, and to a logic low (GND) to disable it.
• How do I handle the power-up sequence when using the TPS2212IDB?
  The power-up sequence should be such that the input sources are powered up before the TPS2212IDB is enabled. This ensures that the device switches to the valid input source.
• What is the role of the PG pin, and how do I use it?
  The PG (power good) pin is an open-drain output that indicates when the output voltage is within regulation. It can be used to monitor the output voltage and generate a reset signal if needed.
