TPS2547: Input voltage range (operating and max)

Jordan Radice

Part Number: TPS2547

Hi e2e,

Can we get confirmation on whether or not the TPS2547 can operate with a nominal input of 5.46V +/-100mV (5.56V peak) with transients up to 5.8V? I understand this is out of the max operating range for the TPS2547, but still below the absolute max, so I wanted to see what your thoughts are here.

Thank you,

Jordan

    Hi Jordan,

    I would strongly advise your customer against such an implementation because anything above 5.5V is not recommended and using an out of threshold voltage could lead to non-ideal performance. Where is the 5.46V coming from? Is this a 5V rail that is connected to other devices on the system that need the 5.46V?
