It operates from a 2.7 V to 5.5 V input rail and switches at a fixed 2 MHz, allowing small external inductors and capacitors. Typical applications include powering dual voltage rails in portable devices, wireless modules, and low-power embedded systems where board space is tight. ## 2 MHz switching — small passives, but watch the layout The 2 MHz switching frequency shrinks the inductor and output capacitor values, which helps fit the design into a compact PCB area. ## Lifecycle — obsolete, but still sourced The LM3370SD-3806/NOPB is marked obsolete by Texas Instruments. For new designs, a current-production single-output buck like the LMR33630 or LM53625 may be considered, but these are single-output parts with different pinouts and package options.","metaTitle":"LM3370SD-3806/NOPB Dual Buck Regulator, 600mA, 2MHz","metaDescription":"LM3370SD-3806/NOPB dual 600mA step-down buck regulator, 2.7-5.5V input, fixed 1.6V/1.8V outputs, 2MHz switching, 16-WSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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)":"1.6V, 1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6800","priceTiers":[{"qty":444,"price":"$0.68000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d8a16d8af847807ec48abad09efd1173.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3370SD-3806%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is a replacement for LM3370SD-3806/NOPB?","answer":"There is no direct pin-compatible replacement from TI.
