That switch current rating is the headline number: it tells you the inductor peak current the part can handle before the cycle-by-cycle current limit folds back. For a typical 3.3V to 5V conversion at 2A output, the inductor peak sits around 4A — leaving margin before the 6.5A limit, which keeps the design out of current-limit foldback during load transients. Input range runs from 2.3V up to 4.9V, so this part works from a single Li-ion cell (3.0-4.2V), two alkaline cells in series (2.4-3.0V), or a regulated 3.3V or 5V bus. The minimum 2.3V input lets it keep running as the battery discharges below 3V, which is where many boost converters drop out. Output is adjustable from a 2.9V minimum up to 5.5V maximum, covering the common 3.3V and 5V rails plus intermediate voltages for USB OTG or sensor bias. The 1MHz switching frequency keeps the inductor and output capacitor small — a 2.2 µH to 4.7 µH shielded inductor is typical for this class. ## 125°C junction and synchronous rectification The 125°C Tj limit sets the derating curve: at 105°C ambient the available output current is lower than at 25°C, so the thermal budget needs to be checked against the load profile. The synchronous rectifier eliminates the external Schottky catch diode and improves efficiency at light loads — expect 90%+ efficiency in the 100 mA to 1 A range. The single positive output with adjustable feedback gives flexibility for non-standard voltages, but the 2.9V minimum output means this part cannot generate a 1.8V or 2.5V rail — that would require a different topology. For a 5V output at 2A, the 6.5A switch rating provides about 30% headroom above the calculated peak current, which is a comfortable margin for transient response without oversizing the inductor. The part is surface-mount, so the standard reflow profile for a 9-VFQFN applies; no special moisture sensitivity level is listed in this record, but the small 2.5x2.5 mm pad array is straightforward for a pick-and-place line.","metaTitle":"TI TPS61236PRWLR Boost Converter, 6.5A Switch","metaDescription":"Texas Instruments TPS61236PRWLR step-up DC-DC converter. 6.5A switch, 2.3V to 4.9V input, adjustable output to 5.5V.","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-Up","Topology":"Boost","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"9-VFQFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"6.5A (Switch)","Number of Outputs":"1","Base Product Number":"TPS61236","Output Configuration":"Positive","Frequency - Switching":"1MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"4.9V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"9-VQFN-HR (2.5x2.5)","Voltage - Output (Min/Fixed)":"2.9V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/59e693ae2837a4a57b41263268e3050e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum output current of TPS61236PRWLR?","answer":"The integrated switch is rated for 6.5A peak current. The actual maximum output current depends on the input-to-output voltage ratio and inductor selection — for a 3.3V to 5V conversion, expect up to about 2A continuous output before hitting the switch current limit.
