TPS7H5005-SEP: TPS7H5005-SEP

Part Number: TPS7H5005-SEP

Tool/software:

The TPS7H5005-SEP data sheet mentions VREF is measured at COMP.  How is this measurement made?

Since its measured at COMP of the Error Amplifier I believe this indicates the 2mV input offset voltage is then part of the VREF min max tolerance.  

Please comment.

    Hey Stuart,

    The VREF is measured by slowly increasing the VREF pin and waiting for the COMP pin to go to 0 V.
    This would incorporate an error amplifier offset in the measurement.

    The offset is measured by looking at the internal reference rail change.

    Thanks,
    Daniel
