Thought for 1 min 31 sec
Here are three Digi-Key-available SMD buck converters that meet your 20–24 V in, 5 V out @ ≥ 2.5 A, UVLO & OVP requirements:
Table
| Part | MPN | Flux Library Link | Datasheet | Key Specs |
|---|---|---|---|---|
| Texas Instruments TPS54331 | TPS54331DRCR | TPS54331DRCR | Datasheet | Vin up to 36 V; Vout fixed 5 V; 3 A; QFN-20; UVLO & OVP |
| Maxim Integrated MAX17503 | MAX17503EUA+T | MAX17503EUA+T | Datasheet | Vin up to 60 V; Vout adjustable (5 V); 3 A; Synchronous buck; UVLO & OVP |
| Texas Instruments TPS54360 | TPS54360DRCT | TPS54360DRCT | Datasheet | Vin up to 36 V; Vout adjustable (5 V); 3 A; HTSSOP-20; UVLO & OVP |
Recommendation
- Primary: TPS54331 for its simple fixed-5 V option, proven performance, and broad 36 V input headroom.
- Alternate: MAX17503 if you need extra input-voltage margin (up to 60 V).
Let me know if you need specific UVLO/OVP threshold values or help dropping one of these into your schematic!
