Product details

Obsolete — last-time-buy planning needed

The LM2576HVT-3.3/NOPB is listed as Obsolete per the manufacturer's lifecycle status. Plan your BOM for a cross to a pin-compatible alternative before committing to a new production run.

60 V input, 3 A output — wide-range step-down

This is a fixed 3.3 V output buck regulator from the SIMPLE SWITCHER® family, rated for 3 A continuous output. The input range spans 4 V to 60 V, making it suitable for unregulated supplies in industrial and automotive environments where the rail can swing well above the nominal. Switching frequency is 52 kHz. The TO-220-5 through-hole package handles the thermal load of a 3 A step-down without a heatsink in moderate airflow.

The through-hole TO-220-5 package is straightforward to hand-assemble or rework — no hot-air profile needed.

Sourcing reality for an obsolete part
