The '2+1' indicates two phases for the core rail and one phase for the graphics rail, matching the IMVP7 (Intel Mobile Voltage Positioning 7) specification for processor power delivery. This is a dedicated controller IC, not a standalone regulator — it requires external MOSFETs and inductors to form the complete converter. ## Active lifecycle — no end-of-life concern for new designs For a BOM line feeding a production run of notebook or embedded motherboard designs, this part does not carry the obsolescence risk that drives last-time-buy logistics or broker premiums. The active status also means datasheets, application notes, and design tools remain available through the standard TI portal. ## Rework and handling notes for the bench As a dedicated CPU controller in a surface-mount package, the TPS51640RSLT is reworkable with standard hot-air equipment. The part's orientation marking (pin 1 indicator) is critical for correct placement; verify it against the datasheet footprint before reflow. The thermal pad under the package needs a good solder joint to the board's ground plane for heat sinking — a poor rework here can lift the pad or leave a void that degrades thermal performance. If you are hand-replacing this on a board, preheat the board to 100-120°C to reduce thermal shock and avoid lifting adjacent passives.","metaTitle":"TI TPS51640RSLT IMVP7 CPU Controller, Active","metaDescription":"Texas Instruments TPS51640RSLT 2+1 IMVP7 CPU controller.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"series":"*","has_mpn":"TPS51640","package_type":"Bulk","product_status":"Active","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.74","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5fae89a9c06eac1a10d584e9d2a5ae5e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy TPS51640RSLT?","answer":"Submit a quote request for current pricing and availability — no stock or price figures are published here because market conditions vary by quantity and delivery timeline."},{"question":"What is the TPS51640RSLT used for?","answer":"The TPS51640RSLT is a 2+1 IMVP7 CPU controller used to power Intel mobile processor core and graphics voltage rails in notebook and ultrabook platforms.
