The Texas Instruments LM2594HVM-12/NOPB is a SIMPLE SWITCHER® non-synchronous step-down regulator that delivers a fixed 12 V output at up to 500 mA from a wide input range of 4.5 V to 60 V.
The 8-SOIC package has no exposed pad.
The LM2594HVM-12/NOPB is an active, in-production part with no last-time-buy risk. It is ROHS3 compliant. The /NOPB suffix indicates lead-free (Pb-free) finish.
The LM2594HVM-12/NOPB is a functional replacement for the LM2594-12 with the same fixed 12 V output and 500 mA rating, but the HVM version extends the input voltage to 60 V (versus 40 V for the standard LM2594-12) and the /NOPB suffix ensures lead-free finish. Verify the pinout and package compatibility for your specific board — both are 8-SOIC.
The /NOPB suffix on LM2594HVM-12/NOPB indicates a lead-free (Pb-free) finish, compliant with ROHS3. The LM2594HVM-12 (without /NOPB) may have a tin-lead finish. Electrically the two are identical — same 60 V input, fixed 12 V output, 500 mA, 150 kHz, and 8-SOIC package.
