The LM2630MTCX-ADJ is a switching controller from National Semiconductor, designed for DC-DC conversion where the output voltage needs to be set by external resistors rather than fixed internally. The 'ADJ' suffix confirms it is the adjustable version, giving the designer flexibility to dial in a specific output voltage for the load.
Lifecycle and compliance reality
There is no NRND or EOL flag to worry about for new designs. One catch: it is RoHS non-compliant, which means it contains lead (Pb) and cannot be used in assemblies destined for markets that enforce RoHS exemptions — think military, aerospace, or medical where leaded solder is still permitted, but not commercial consumer goods shipping to the EU or California.
Sourcing posture
Because this part is Active and RoHS non-compliant, it occupies a specific niche: designs that need the adjustable controller but can tolerate leaded solder. Submit an RFQ and we will come back with a firm price and delivery window.
