The synchronous rectifier improves efficiency at moderate loads, and the single positive output is set at 5V with no external divider resistors needed. ## What the 500 mA switch limit means for your load budget The 500 mA switch current limit is the peak current the internal power FET can handle during each switching cycle. For a boost converter, the output current capability depends on the input-to-output voltage ratio: at 5V output from a 3.3V input, expect around 300–350 mA continuous output before the switch hits its limit. If your load draws more than that, you either step up to a higher-current boost or add a second stage. The 3.5 MHz switching frequency lets you use a 1 µH inductor and a 4.7 µF output capacitor, keeping the total solution area under 15 mm². ## 6-DSBGA package — plan the board layout early The part comes in a 6-bump DSBGA (wafer-level chip-scale) package. The bumps are on a 0.5 mm pitch, and the package itself is roughly 1.3 mm × 0.9 mm.","metaTitle":"TPS61240YFFT Boost Converter, Fixed 5V Output, 3.5MHz","metaDescription":"Texas Instruments TPS61240YFFT step-up (boost) DC-DC converter, fixed 5V output, 500 mA switch, 3.5 MHz switching, 6-DSBGA package, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up","Topology":"Boost","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-UFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"500mA (Switch)","Number of Outputs":"1","Base Product Number":"TPS61240","Output Configuration":"Positive","Frequency - Switching":"3.5MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"-","Supplier Device Package":"6-DSBGA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f27148026a541e7cdb826797ab1f865a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61240YFFT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61240YFFT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61240YFFT when reusing this data.
