TPS40090-Q1: Accuracy

Part Number: TPS40090-Q1

Hi, 

I would like to know the exact accuracy of this DC to DC in High Temperatures.

Thank you for your support, 

Anna

    Hi Anna,

    You can estimate the total output accuracy by combining the error amplifier reference accuracy (-1.5% to +1.0%), the remote sense amplifier accuracy (-0.5% to +0.5%), and the resistor accuracy of your feedback divider (typically +/- 1%).

    If this application uses load line, then you need also to consider the (1) DCR tolerance of the inductor, (2) accuracy of the current sense amplifier (-13% to +10% gain/ (-7 to +8mV offset), and the droop current accuracy.
