Efficiency peaks above 90 % at moderate loads, and the 2 MHz switching keeps ripple well below 20 mVpp with a proper output cap. Operating temperature range is -30°C to 85°C ambient, which covers most portable and industrial indoor applications but does not extend to automotive under-hood or extended outdoor enclosures. The thermal pad junction-to-ambient thermal resistance (RθJA) is typically 40 °C/W when the pad is soldered to a 1 in² copper area on a 2-layer board. The part is ROHS3 compliant (lead-free, no exemptions), and the suffix /NOPB confirms the lead-free finish. For volume pricing and lead time, submit an RFQ against your BOM quantity. This is a current-production TI part, so lead times typically run 8–12 weeks through authorized channels; spot-market availability may be tighter. No direct second-source or pin-compatible alternative is listed by TI — the base product number LM3370 covers several fixed-output voltage variants, but the -3021 suffix is specific to the 1.2 V / 3.3 V combination.","metaTitle":"LM3370SD-3021/NOPB Texas Instruments Dual 600mA Buck","metaDescription":"Texas Instruments LM3370SD-3021/NOPB dual step-down buck regulator, 600 mA per output, 2 MHz switching, fixed 1.2V/3.3V outputs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","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":"Active","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":[{"qty":1,"price":"$1.82000","currency":"USD"},{"qty":10,"price":"$1.63200","currency":"USD"},{"qty":25,"price":"$1.53960","currency":"USD"},{"qty":100,"price":"$1.31180","currency":"USD"},{"qty":250,"price":"$1.23172","currency":"USD"},{"qty":500,"price":"$1.07776","currency":"USD"},{"qty":1000,"price":"$0.89300","currency":"USD"},{"qty":2000,"price":"$0.87150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/07e3d7353ec72bea3806cd32612099ea.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3370SD-3021%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the LM3370SD-3021/NOPB in the same family?","answer":"The base product number LM3370 covers several fixed-output voltage variants (e.g., LM3370SD-3020/NOPB with different output voltages).
