The adjustable output version sets its voltage via two external resistors from a 1.23 V reference up to 57 V. This 60 V input ceiling covers 24 V industrial rails with margin for load-dump transients, 48 V telecom buses, and 12/24 V automotive systems — the 3 A output handles auxiliary rails, sensor supplies, and local point-of-load regulation. ## 52 kHz switching — the inductor size trade-off The fixed 52 kHz switching frequency is low by current-generation standards. That means the external inductor and output capacitor will be physically larger than what a 200 kHz+ switcher would need — roughly 100 µH to 330 µH for typical 3 A designs. The trade-off is lower switching losses and simpler EMI management: the fundamental and its harmonics sit well below the AM broadcast band, and the layout is less sensitive to parasitic capacitance. For a board that already has space, the 52 kHz SIMPLE SWITCHER topology is forgiving and well-documented. The part does not use synchronous rectification — it relies on an external Schottky catch diode. At 3 A output, the diode forward drop dominates the thermal budget; a 3 A, 60 V Schottky in a D²Pak or similar is the standard companion. The 52 kHz rate keeps diode heating manageable, but the diode must be rated for the full 60 V input plus switching ringing margin. ## NRND — still available, but plan the transition No official last-time-buy date or successor part number is recorded on this listing. For existing BOM lines already qualified, the part remains a valid procurement choice while channel inventory lasts. For new designs, a more modern pin-compatible or functionally equivalent buck regulator should be evaluated before the layout is frozen. ## Package and temperature grade — DDPAK for the power loop The tab is the primary heat path: at 3 A output and a typical 12 V to 5 V conversion, the die dissipates roughly 2–3 W, demanding a 1 in² copper area on a 2 oz board to keep TJ below 125°C.","metaTitle":"LM2576HVS-ADJ SIMPLE SWITCHER Buck Regulator","metaDescription":"LM2576HVS-ADJ SIMPLE SWITCHER step-down regulator, 60V input max, 3A output, adjustable 1.23V to 57V, -40°C to 125°C, TO-263-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"SIMPLE SWITCHER®","Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-263-6, D²Pak (5 Leads + Tab), TO-263BA","Product Status":"Not For New Designs","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)":"57V","Supplier Device Package":"DDPAK/TO-263-5","Voltage - Output (Min/Fixed)":"1.23V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.2981","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/74e216c81e85fc39d2b33ae4761c412c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2576HVS-ADJ/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM2576HVS-ADJ?","answer":"No official replacement or successor part number is recorded on this listing.

It can be configured via feedback resistors to produce a fixed 12 V output, making it a functional replacement for the LM2576HVS-12 in most designs — just add the two external resistors.
