At 3A continuous, plan for a heatsink with adequate airflow — the tab dissipates the bulk of the conduction loss. ## No synchronous rectifier — external Schottky required The LM2576T-15 uses an asynchronous (non-synchronous) topology — a catch diode, typically a 3A Schottky, must be added externally. This is standard for the SIMPLE SWITCHER family: the datasheet recommends a 1N5822 or equivalent. The external diode adds BOM cost and board area but simplifies the design by eliminating the dead-time control loop.","metaTitle":"LM2576T-15 SIMPLE SWITCHER® Step-Down Regulator, 3A, 52 kHz","metaDescription":"Texas Instruments LM2576T-15 SIMPLE SWITCHER® buck regulator, 3A output, 52 kHz switching, fixed 15V, 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)":"40V","Voltage - Input (Min)":"4V","Voltage - Output (Max)":"-","Supplier Device Package":"TO-220-5","Voltage - Output (Min/Fixed)":"15V"}},"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/LM2576T-15/alternatives.json"},"ai":{"faq":[{"question":"What is the switching frequency of LM2576T-15?","answer":"The switching frequency is 52 kHz, typical for the SIMPLE SWITCHER family.
