PWM step-down regulator — what it is and where it fits
The MAX1572ETC180 is a PWM DC-to-DC step-down converter from Maxim Integrated. It suits point-of-load applications where linear dropout would waste too much power.
Lifecycle and compliance — active, but watch the RoHS flag
No NRND or EOL notice to worry about for new designs. The catch: it is RoHS non-compliant. That means the part uses lead-bearing solder termination, which rules it out for any assembly line that requires full RoHS exemption-free compliance. If your BOM calls for lead-free reflow or your end product must carry a RoHS declaration, this part will not pass — you need the RoHS-compliant variant in the same family. For designs that can accept SnPb finish (military, aerospace, or legacy industrial rework), the active status means supply continuity is solid.
Sourcing — quoted to order
Because the part is active and has a known non-compliance constraint, sourcing is straightforward: we confirm availability and current pricing at quote time against an RFQ. The active status means no last-time-buy scramble, but the RoHS restriction narrows the pool of buyers — so stock turns may be slower, and a distributor holding bulk inventory may be willing to negotiate on volume. If your line needs a reel or a specific date-code range, mention it in the RFQ so we can match from what is on the shelf.
