What this white LED power supply is and where it fits
The Maxim Integrated MAX1578ETG is a white LED power supply IC, designed to drive and regulate the current through white LEDs in backlighting or illumination applications. Its function is to provide a regulated voltage or current rail from a battery or low-voltage input, typical in portable displays, handheld instruments, and automotive infotainment panels where consistent LED brightness is required.
Lifecycle and compliance — what it means for your BOM
However, the part is marked RoHS non-compliant, which is a hard constraint for designs subject to the RoHS directive or for customers requiring lead-free assembly. If your BOM calls for a lead-free bill, this part will not pass inspection — plan for a RoHS-compliant alternate or a documented exemption.
Sourcing this part for production
Because the MAX1578ETG is active but RoHS non-compliant, it tends to move through channels that handle legacy or exempt-class components. We source it to order against an RFQ through independent distribution, confirming availability and current pricing at quote time. For a BOM line that needs this exact order code, the procurement path is straightforward: submit an RFQ, and we will quote the best available date-code spread and pricing from our sourcing network.
