It takes a 4.5 V to 16 V input, covering the common 5 V and 12 V intermediate bus rails used in industrial control, telecom line cards, and networking equipment. The two outputs can be sequenced independently, which matters when a processor core must power up before its I/O rail. ## Switching frequency — inductor size vs efficiency trade At the low end, efficiency peaks but the inductor footprint grows; at the high end, the inductor shrinks to a 2.2 µH or 1 µH part, which helps on a dense 28-VFQFN layout. The synchronous rectifier keeps the efficiency curve flat across load — expect 85-90% range depending on the frequency and duty cycle chosen. ## Package and thermal — the exposed pad is your heat path The 3 A channel will need airflow or a copper pour area of at least 1 in² on the inner layer to keep junction temperature below the 125°C limit at full load. ## Lifecycle — no obsolescence watch needed The base product number TPS65252 covers a family of dual-output regulators; the RHDT suffix denotes the 28-VFQFN package and Tape & Reel shipping format.","metaTitle":"TPS65252RHDT Dual Buck Regulator, 3A/2A, 300kHz-2.2MHz","metaDescription":"Texas Instruments TPS65252RHDT dual-output step-down buck regulator. 3A and 2A adjustable outputs, 4.5V-16V input, 300kHz-2.2MHz switching, -40°C to 85°C.","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":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"28-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A, 2A","Number of Outputs":"2","Base Product Number":"TPS65252","Output Configuration":"Positive","Frequency - Switching":"300kHz ~ 2.2MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"16V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"15V","Supplier Device Package":"28-VQFN (5x5)","Voltage - Output (Min/Fixed)":"0.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5de3f2443b107eee0181a56482e0f91e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65252RHDT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS65252RHDT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS65252RHDT when reusing this data.
