The 1.25 MHz switching frequency lets the designer use small-value inductors and ceramics, keeping the total solution footprint tight for space-constrained boards. ## Switching frequency and inductor sizing At 1.25 MHz, the typical inductor value falls in the 2.2 µH to 4.7 µH range. The fixed switching frequency also places the fundamental ripple above the AM broadcast band, which simplifies input-filter design in noise-sensitive equipment. ## Synchronous rectification and efficiency","metaTitle":"TPS62043DRCR Buck Converter, 1.2A, 1.25MHz, 10-VSON","metaDescription":"Texas Instruments TPS62043DRCR step-down buck converter, 1.2A output, 1.25MHz switching, synchronous rectifier, -40°C to 85°C, 10-VSON (3x3).","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":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","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-VSON (3x3)","Voltage - Output (Min/Fixed)":"1.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1445","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a54d04aa330c6ddd3c5f782f778189e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62043DRCR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62043DRCR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62043DRCR when reusing this data.
