Wrong L1 inductance? #1

Closed T94T closed 8 months ago

T94T commented 2 years ago

Shouldn't L1 be 3.9μH as mentioned in the datasheet? 4.7μH seems to be for the AP63205.

@T94T seems so.

Ok, we replaced the inductor with a 3.9μH one.

adamgarbo commented 1 year ago

You could have left the issue open for SparkFun to address.

Did you notice any significant difference in the output after changing the inductor?

T94T commented 1 year ago

There was no noticeable difference, but we didn't make any more precise measurements either.

Were you seeing any issues? Using a slightly larger inductor shouldn't be an issue and according to the datasheet may improve efficiencies at lighter loads.

T94T commented 8 months ago

3.9μH is the value we go for.
