The synchronous rectifier (no external Schottky diode needed) keeps the BOM count low, and the fixed output voltages mean no feedback divider resistors on the board. For a production BOM, this part is a single-source risk — you will need to qualify a replacement or source remaining stock through independent distribution. ## Package and thermal — 16-WSON exposed pad The 2 MHz switching frequency pushes the switching losses, but the synchronous rectifier helps efficiency — layout should keep the switch node loop small to minimise radiated noise.","metaTitle":"LM3370SD-3621/NOPB Dual Buck Regulator, 2 MHz, Obsolete","metaDescription":"Texas Instruments LM3370SD-3621/NOPB dual step-down buck regulator, 2.7-5.5V input, fixed 1.5V/3.3V outputs, 600 mA per channel, -30°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"16-WFDFN Exposed Pad","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Output":"600mA","Number of Outputs":"2","Base Product Number":"LM3370","Output Configuration":"Positive","Frequency - Switching":"2MHz","Operating Temperature":"-30°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"-","Supplier Device Package":"16-WSON (5x4)","Voltage - Output (Min/Fixed)":"1.5V, 3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d36e07764e9d1dcd8a4da3b5c605c8b2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3370SD-3621%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3370SD-3621-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/LM3370SD-3621-NOPB when reusing this data.
