It switches at 150 kHz and operates over a -40°C to 125°C junction temperature range, making it suitable for industrial, automotive, and telecom power rails that need a regulated 12 V bus from a high-voltage or widely varying input source. ## Temperature grade and environment The -40°C to 125°C junction temperature rating covers outdoor telecom cabinets, engine-bay electronics, and factory-floor power supplies without derating. The 8-SOIC package has no exposed pad. ## Lifecycle and sourcing 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.","metaTitle":"LM2594HVM-12/NOPB SIMPLE SWITCHER® Buck Regulator","metaDescription":"Texas Instruments LM2594HVM-12/NOPB SIMPLE SWITCHER® step-down regulator, fixed 12V output, 500mA, 60V input max, 150kHz, -40°C to 125°C, 8-SOIC.
