Synchronous rectification eliminates the external Schottky diode, improving efficiency at light loads and reducing component count. Input voltage spans 1.8V to 5.5V, covering single-cell Li-ion (2.7-4.2V), two alkaline cells, or a regulated 5V rail — the part transitions seamlessly between buck and boost modes around the output setpoint. Output is adjustable from 1V up to 5.2V, or a fixed voltage option is available — the adjustable version uses an external resistor divider to set the regulation point. ## Active production and compliance ROHS3 compliant, the part meets the latest EU restriction requirements for lead, mercury, cadmium, and phthalates — no exemption declarations needed for EU-market shipments.","metaTitle":"ISL91127IRAZ-T7A Buck-Boost Regulator, 2A, 2.5MHz, 20-QFN","metaDescription":"ISL91127IRAZ-T7A step-up/step-down regulator, 1.8V-5.5V input, 2A output, 2.5MHz switching, synchronous rectification, active production, ROHS3, 20-QFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up, Step-Down","Topology":"Buck-Boost","Output Type":"Adjustable (Fixed)","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"2.5MHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"1.8V","Voltage - Output (Max)":"5.2V","Supplier Device Package":"20-QFN (4x4)","Voltage - Output (Min/Fixed)":"1V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.37","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.37000","currency":"USD"},{"qty":10,"price":"$3.02700","currency":"USD"},{"qty":25,"price":"$2.86200","currency":"USD"},{"qty":100,"price":"$2.48040","currency":"USD"},{"qty":250,"price":"$2.35320","currency":"USD"},{"qty":500,"price":"$2.11152","currency":"USD"},{"qty":1250,"price":"$2.00400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/015fc2255fc98419dd1ea798a1fbb4fa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the ISL91127IRAZ-T7A used for?","answer":"It is a synchronous buck-boost regulator that steps voltage up or down from a single input — ideal for battery-powered devices where the battery voltage crosses the system rail, such as IoT sensors, wearables, and portable instruments that need a stable 3.3V or 5V rail from a Li-ion cell."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/ISL91127IRAZ-T7A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/ISL91127IRAZ-T7A when reusing this data.
