LM73605-Q1: Is the tolerance on the feedback voltage correct?

Tony Nguyen2

Part Number: LM73605-Q1

In the datasheet, the tolerance on the feedback voltage is -1% and +2% - not symmetrical. I would like confirmation because the DC-DC design is failing WCCA.

What specification are you referring to?

The EC table shows the following for VFB:

min=0.987

typ=1.006

max=1.017

This would give a -1.88% and +1.1% from typ.

Whoops, yes thanks for the catch. Mixed up the signs, meant to say +1% and -2% (rounded). Can you confirm these numbers?
