It integrates a synchronous rectifier for higher efficiency in the load range typical of low-voltage logic rails — think 1.8V VDD for DDR memory terminations, FPGAs, or MCU I/O banks in portable or embedded systems. The 1.25MHz switching frequency keeps the inductor small, around 4.7 µH to 10 µH, which helps when board area is tight. ## Obsolete — no new designs here That means Texas Instruments has ended production; there is no last-time-buy window remaining through the authorized channel. No official successor is listed on the record, so a pin-compatible drop-in replacement is not confirmed from the manufacturer. If this is a new design, skip this part and look at current TI buck converters in the same 1.2A / 6V input class. ## 10-VSON footprint and thermal reality The TPS62044DRCRG4 comes in a 10-VFDFN Exposed Pad package (supplier device package 10-VSON, 3x3 mm). The 1.25MHz switching edge also makes the input loop layout critical: keep the input capacitor (10 µF ceramic recommended) within a few millimetres of the VIN and PGND pins to avoid ringing that eats into efficiency.","metaTitle":"TPS62044DRCRG4 Step-Down Regulator, 1.2A, 1.25MHz, Obsolete","metaDescription":"Texas Instruments TPS62044DRCRG4 buck regulator, 1.2A output, 1.25MHz switching, 2.5V-6V input, fixed 1.8V output.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"10-VFDFN Exposed Pad","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Output":"1.2A","Number of Outputs":"1","Base Product Number":"TPS620","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a54d04aa330c6ddd3c5f782f778189e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62044DRCRG4/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62044DRCRG4 obsolete?","answer":"Yes, the TPS62044DRCRG4 is listed as Obsolete.
