Switching at 2 MHz, it uses synchronous rectification to keep external inductor and capacitor values small — the 2 MHz rate pushes switching noise above the AM band, which helps in RF-sensitive layouts. ## Package and thermal considerations for layout The 20-DSBGA package requires microvia fan-out under the BGA. The operating temperature range is -30°C to 85°C, which covers most consumer and industrial indoor environments but not extended automotive or military. Synchronous rectification improves efficiency at light loads, but the 2 MHz switching means the power-stage loop must be tight — keep the input capacitor close to the PVIN pins and the inductor return path short. The fixed output voltages (1.2 V, 1.8 V) eliminate feedback resistor dividers, saving two resistors per rail. ## How it compares to single-output automotive peers The LMR33630APCQRNXRQ1 is a single 3 A adjustable-output buck with wettable flanks for AOI, also automotive-grade. Neither is a drop-in replacement — the LM3370 is distinct for its dual fixed-rail output in a small BGA.","metaTitle":"LM3370TLX-3006/NOPB – Texas Instruments Dual Buck Regulator","metaDescription":"Texas Instruments LM3370TLX-3006/NOPB dual step-down buck regulator, 2.7 V to 5.5 V input, fixed 1.2 V and 1.8 V outputs at 600 mA each.","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)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"20-WFBGA","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":"20-DSBGA","Voltage - Output (Min/Fixed)":"1.2V, 1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0900","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/LM3370TLX-3006%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3370TLX-3006/NOPB?","answer":"Texas Instruments has not published an official successor for the LM3370TLX-3006/NOPB.
