This makes it a single-inductor isolated or non-isolated supply for industrial and automotive auxiliary rails where the input bus varies widely — a 12V truck battery at rest (~12.5V) versus a 24V industrial rail, or a 48V telecom bus stepped down through the same part. ## Switching frequency and thermal envelope The switching frequency spans 12kHz to 350kHz, set by an external resistor. A lower frequency reduces switching losses and eases EMI filtering but demands a larger transformer; 350kHz shrinks the magnetics at the cost of higher core loss. The 8-WSON package with exposed pad (4x4 mm) and wettable flank terminals supports automated optical inspection of the solder joints — a requirement for automotive-grade assembly lines. ## Active production, ROHS3 compliant The part is available in Tape & Reel (TR) or Cut Tape (CT) packaging — the TR suffix on the order code indicates reel packaging for automated pick-and-place; the CT option suits prototype or low-volume builds.","metaTitle":"TI LM25184NGUR Flyback Regulator, 12V 4.1A, 8-WSON","metaDescription":"Texas Instruments LM25184NGUR flyback regulator, fixed 12V output at 4.1A, 4.5V-42V input, 8-WSON package.
