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","metaTitle":"LM2576HVT-3.3/NOPB SIMPLE SWITCHER® Buck Regulator, 3A","metaDescription":"Texas Instruments LM2576HVT-3.3/NOPB SIMPLE SWITCHER® step-down regulator, 3A output, 52kHz, TO-220-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"SIMPLE SWITCHER®","Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-220-5","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Base Product Number":"LM2576","Output Configuration":"Positive","Frequency - Switching":"52kHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"60V","Voltage - Input (Min)":"4V","Voltage - Output (Max)":"-","Supplier Device Package":"TO-220-5","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/74e216c81e85fc39d2b33ae4761c412c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2576HVT-3.3%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2576HVT-3.3-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM2576HVT-3.3-NOPB when reusing this data.
