TRS3122E: TRS3122ERGER at 3.3Vcc what is the max current draw?

Part Number: TRS3122E

Hello Team,

My customer would like to understand what the max power consumption is for the TRS3122ERGER with Vcc of 3.3V?  He's looking to understand how much current draw the part will have so he can size the power supply provided accordingly.  Please advise.

If there is a spec in the datasheet that I should look at for future reference please advise as I'm not sure if the output short circuit current is the right one I should be looking at??? (120mA??)

Sincerely,

Dan Nitta Mackay TSR

    Hi Dan,

    The supply current will vary with several factors like supply voltage, switching rate, and load capacitance. You can get some idea what to expect by looking at Figures 1 through 6 in the datasheet. If you want us to evaluate it at a specific set of conditions for your customer please let us know.

    Best regards,
    Max
