You can design and make your own inductor using a suitable core recuperated from old equipment if you have the knowledge, practical experience and equipment for this task. The chip includes a 3A NPN switch transistor with its associated protection circuitry, consisting of current and thermal limiting, and undervoltage lockout.

Chip One Stop The design uses the adjustable version of LM, but the 12V fixed-voltage version LMT will also work if you remove R1 and R2 and connect the feedback pin directly to the dahasheet output.
