Inductor Selection for Buck-Boost Regulator
Thought for 1 min 11 sec

A good match is CSBX1670-220M.
Recommended inductor
Table
| Part | Inductance | Current | DCR | Type | Why it fits |
|---|---|---|---|---|---|
| CSBX1670-220M | 22 µH | 8.5 A | 23.5 mΩ max | Shielded wirewound SMD | Lands in your 15 to 30 µH target and stays comfortably above your 6.3 A limit |
This is the cleanest fit I found for your updated requirement:
- inductance in range: 22 µH
- current capability above your ceiling: 8.5 A
- shielded power inductor
- reasonable DCR for this value/current class
If you want, I can next narrow it further by:
- smallest footprint
- lowest DCR
- best availability/cost
Or I can help choose whether 15 µH, 22 µH, or 30 µH is best for your exact buck-boost operating point.
