That 60 V ceiling covers 48 V telecom buses, 24 V industrial supplies, and 12 V automotive systems with headroom for transients — the internal switch is rated for the full input range, so no external clamp is needed for load-dump events up to 60 V. The adjustable output spans 1.2 V to 57 V, set by a resistor divider. The 150 kHz switching frequency is low enough to keep inductor core losses modest but high enough to avoid audible noise in most loads — a 47 µH to 330 µH inductor in the standard SIMPLE SWITCHER design table will get you there. ## Through-hole package and thermal reality For 500 mA at a moderate Vin-Vout differential, the junction stays well within the -40°C to +125°C operating range, but at high differentials (say 48 V in to 3.3 V out) the power loss in the switch and catch diode will push the die temperature; a bit of airflow or a larger copper pad on the board side helps. The part is not synchronous — the external Schottky catch diode is your choice. That means you pick the diode for your output current and reverse voltage, which gives flexibility but adds a BOM line. The 150 kHz switching rate keeps the diode's reverse-recovery loss negligible. It is ROHS3 Compliant — no lead, no restricted phthalates — and ships in a tube.","metaTitle":"Texas Instruments LM2594HVN-ADJ/NOPB Buck Regulator, 500mA","metaDescription":"Texas Instruments LM2594HVN-ADJ/NOPB SIMPLE SWITCHER® step-down regulator, 500 mA output, 60V input, adjustable, 8-DIP.
