LM5069: LM5069 negative output Schottky

Part Number: LM5069

dear Sir 

Do you have any document to describe below output diode's function 

If have the waveform ,it will be better 

Thanks

  • Hi Kai,

    The purpose of the TVS diode and the Schottky diode is for IC protection. We recommend all designs with hot swap controller to have a TVS diode on the input and a Schottky diode at the output (for transients).

    All wires have trace inductance and in the event of a hot short or severe overcurrent, those wires could produce a huge change in voltage at the input and output, which could damage our IC. I recommend the B380-13-F Schottky diode and make sure the TVS diode clamps the voltage lower than the abs max of the device at the worst case clamping current.

    Best Regards,
