Original question:

TPS784-Q1: The accurancy fo TPS784-Q1

TPS784-Q1: Output accuracy

Peter Frost
Prodigy 10 points
Part Number: TPS784-Q1

Tool/software:

Hi,

The front page figure, and Figures 6-1 to 6-10 suggest the output accuracy is within 0.2% across pretty much all operating conditions.

Although in another thread here when referring to these figures, the output accuracy is quoted as ~2.25%, although the Electrical Characteristics table states a maximum of 1.7%. Is there a typo on those figures or am I misinterpreting something?

Many thanks,

    Hi Peter,

    Thank you for asking us!

    Output accuracy is typically within 0.2%, and this provides a good estimate of what to expect on your parts. The characteristic curves section represents typical behavior, with ~30 parts measured under the stated conditions.

    However, output accuracy can be up to 1.7% and remain within spec. The min/max limits are specs and are guaranteed across all recommended operating conditions.

    The 2.25% figure should be 0.225% as it pertains to the version of the datasheet I am looking at.

    Best,
