The 0.50 mm pitch around the perimeter means two-layer boards can fan out the outer pins, but the centre pad requires at least a four-layer stack for effective thermal spreading in continuous 1.2A operation. ## 2.5V to 6V input, fixed 1.8V output at 1.2A Input range is 2.5V minimum to 6V maximum, making it a fit for 3.3V or 5V rails. The output is fixed at 1.8V — no adjustable version in this order code, so the BOM must match that rail exactly. The 1.2A continuous output rating is the thermal design current; the part will deliver the rated current up to 85°C ambient with adequate PCB copper area under the exposed pad. ## 1.25 MHz switching with synchronous rectification The fixed 1.25 MHz switching frequency keeps the inductor and output capacitor small — typical values are 2.2 µH to 4.7 µH and 10 µF ceramic. The 1.25 MHz fundamental is above the AM radio band, which simplifies EMI filtering in noise-sensitive designs.","metaTitle":"TPS62044DRCR Step-Down Buck Regulator, 1.2A, 1.25MHz","metaDescription":"Texas Instruments TPS62044DRCR step-down buck regulator: 2.5V-6V input, fixed 1.8V output, 1.2A, 1.25MHz switching, synchronous rectification.","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":"TPS62044","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)":"1.8V"}},"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/TPS62044DRCR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS62044DRCR replace TPS62043DRCR?","answer":"The TPS62044DRCR and TPS62043DRCR are pin-compatible within the same TPS6204x family, differing only in the fixed output voltage.
