TPS74401 accuracy at low current

Daniel Engeler

Other Parts Discussed in Thread: TPS74401

The TPS74401 specifies an output voltage accuracy of 1% for "50mA < Iout < 3A". What is the accuracy for small currents (0mA to 50mA)?

Thanks,
Daniel

Hi Daniel,

While we expect the 1% accuracy to continue to the very light load conditions, these particular conditions are outside of the test conditions that we use.

Very Respectfully,
Ryan

Hi Ryan

Thank you for your quick reply. An accuracy specification at zero current (or maybe 1mA) would be useful for powering analog rails of FPGAs and microprocessors which at initialization use only little current, but require an accurate voltage nonetheless.

Kind regards,
Daniel
