Q: TPS62200 – feedback voltage accuracy spec by 1800947
On page 7 of the datasheet, there is a 'feedback voltage' specification. The way that I read this specification, this would be the input offset of the high-side of the GM amplifier. Am I correct in my understanding?
My customer is using this device for a DSP rail which requires a 5% source. He is concerned that this +/- 3%, will push him into using 0.1% resistors for the feedback divider.
Yes, the output voltage accuracy (or FB pin voltage accuracy for the adjustable versions) is +/-3%.
As the product page for this device suggests, I would highly recommend your customer use a newer IC, such as the TPS62240 or TPS62230 in their design.
