TPS22914: ramp up time on output

Part Number: TPS22914

Tool/software:

Hi

Kindly let us know the ramp up time on the output of TPS22914BYFPR. We are planning to use two numbers of this for 2.5V and 5V. For our use case 2.5V should ramp up first and stabilize even before 5V reaches 4.75V.. Can this be achieved with this device.

    Hi Prema,

    For the same device, 2.5V power rail will ramp up before 5V reaches 4.75V. We do not have waveform for 2.5V but we do have it for 3.3V. If we compare these two, we will see 5V takes 89us for rise time and 105us as total turn on time and 3.3V takes only 61us rise time and 84 turn on time.

    Yes, this is possible with this device.
