The device operates from -30°C to 85°C ambient. The 600 mA per-channel rating provides enough headroom for a low-power processor plus its peripheral bus, but designs drawing more than 600 mA on either rail will need a higher-current regulator or an external load switch to share the current. The fixed outputs eliminate the external divider network. The 2 MHz switching frequency works with small inductors. No last-time-buy date or official successor order code is recorded in the available lifecycle data. This means the part is no longer manufactured or available through the factory channel; any remaining stock is in the independent distribution network. The 5×4 mm WSON package and fixed-output configuration mean that a pin-compatible replacement would need to match the same footprint and voltage settings — no direct cross is confirmed in the available records.","metaTitle":"LM3370SDX-3021/NOPB Dual Buck Regulator, 2 MHz, 600 mA","metaDescription":"Texas Instruments LM3370SDX-3021/NOPB dual step-down buck converter, fixed 1.2V and 3.3V outputs, 600 mA per channel, 2 MHz switching, -30°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","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)":"1.2V, 3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d36e07764e9d1dcd8a4da3b5c605c8b2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3370SDX-3021%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3370SDX-3021/NOPB?","answer":"No official replacement or pin-compatible alternative is documented in the available lifecycle records.
