At 1.2 A continuous output, this part covers the mid-range of the TPS6204x family. If your downstream load peaks at 1 A, you have 20 % headroom before you hit the limit — enough to cover inrush and transient spikes without oversizing the inductor. ## 10-HVSSOP — the exposed pad is your heat path","metaTitle":"TPS62043DGQ Step-Down Regulator, 1.6V Fixed Output, 1.2A","metaDescription":"Texas Instruments TPS62043DGQ synchronous buck regulator, 1.6V fixed output at 1.2A, 1.25MHz switching, 10-HVSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-PowerTFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"1.2A","Number of Outputs":"1","Base Product Number":"TPS62043","Output Configuration":"Positive","Frequency - Switching":"1.25MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"-","Supplier Device Package":"10-HVSSOP","Voltage - Output (Min/Fixed)":"1.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9123","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a54d04aa330c6ddd3c5f782f778189e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62043DGQ/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62043DGQ a direct replacement for TPS62043DGS?","answer":"The TPS62043DGS shares the same base product number and the same fixed 1.6 V output, but comes in a different package — MSOP-10 versus the HVSSOP-10 of the DGQ suffix. The pinout is the same, but the thermal pad differs; verify the PCB footprint and thermal land pattern before swapping."},{"question":"Does TPS62043DGQ require external compensation?","answer":"No. The part is internally compensated — the datasheet shows the typical application uses only the input cap, output cap, and inductor. No external RC network across the error amp."},{"question":"What package does TPS62043DGQ come in and is it RoHS compliant?","answer":"The package is a 10-lead HVSSOP, also described as 10-PowerTFSOP, 10-MSOP with 0.118-inch body width. The tube packaging is standard for this variant. RoHS compliance is typical for TI's current-production PowerPAD parts, though the evidence does not carry a specific RoHS certificate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62043DGQ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62043DGQ when reusing this data.
