Hi,
Customer has an issue with inductor Acoustic Noise.
Input voltage : Max 150mAh@ Alkaline Battery 2.0~ 3.2V
Output voltage : 17V
Output current : 15 ~ 20mA
Changes to Inductor 10uH products do not remove Acoustic Noise.
It seems to be a problem because of the increased power over the initial design.
1. Please review the schematic.
2. Please recommend the Inductor value.
