The maximum current that can be drawn from the TPS2211IDB is 1.5A, but it's recommended to limit the current to 1A for reliable operation.
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.
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.
The power-up sequence should be such that the input sources are powered up before the TPS2211IDB is enabled. This ensures that the device switches to the valid input source.
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.
