What this 5A automotive buck brings to the board
The integrated synchronous rectifier eliminates the external catch diode.
Key specs that drive the BOM decision
The 5A output is the headline number for inductor and output capacitor sizing. At 5A continuous, you need a low-DCR inductor rated for at least 6A saturation and output caps with enough ripple-current headroom. The 36V maximum input means it survives load-dump transients on a 12V automotive rail without external clamping, but on a 24V system check the margin against worst-case alternator surge. The wettable-flank package (30-WQFN with exposed pad) is a practical advantage for automotive production: it allows automated optical inspection of the solder joints on the bottom-side terminals, which a standard QFN hides. That saves a manual X-ray step in the line.
No end-of-life notification or last-time-buy schedule is on record.
The 30-WQFN (6x4 mm) exposed-pad package has an MSL rating that should be verified before reflow.
