The output is adjustable from 2.9 V up to 5.5 V, so it can produce a regulated 3.3 V rail or a 5 V USB power bus from a single cell. ## Switching frequency and package Switching at 1 MHz, the TPS61236RWLT lets you use a small inductor and ceramic capacitors — the 1 MHz rate keeps the ripple current low enough that the output capacitor bank can be 10 µF class, saving board space in a compact handheld or IoT endpoint. The synchronous rectifier improves efficiency by replacing the external Schottky diode with an internal low-side FET — expect >90 % efficiency across most of the load range, though the exact number depends on the inductor and input voltage. Housed in a 9-pin VFQFN package measuring 2.5 mm × 2.5 mm, this is a small-footprint part — the 0.50 mm pitch demands careful solder-paste stencil design and a good thermal via pattern under the exposed pad to pull heat out of the switch. ## Obsolete — sourcing reality The TPS61236RWLT is listed as obsolete. That means Texas Instruments has stopped manufacturing it — no last-time-buy window remains open, and the only available units are those already in the distribution channel or on the spot market. If you need a pin-compatible drop-in, expect to requalify the board — the TPS6123x family shares the same base number but the RWLT suffix is unique to this variant, and TI's current boost portfolio (e.g. TPS61089 or TPS6125x) uses a different pinout and package. Sourcing this part means working with an independent distributor who can verify date-code authenticity and screen for counterfeit units — the spot market for obsolete TI boost converters carries risk, and a known-good date-code lot from the original TI factory is the only safe buy.","metaTitle":"TI TPS61236RWLT boost converter, 6.5A switch, obsolete","metaDescription":"Texas Instruments TPS61236RWLT step-up boost converter, 6.5A switch, 1 MHz, adjustable output to 5.5V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","lifecycle_stage":"eol_hot","Current - Output":"6.5A (Switch)","Number of Outputs":"1","Base Product Number":"TPS612","Output Configuration":"Positive","Frequency - Switching":"1MHz","Operating Temperature":"-40°C~85°C(TA)","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":"$58.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c86fe579f915d61f7a655680b53d6e77.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TPS61236RWLT obsolete?","answer":"Yes, the TPS61236RWLT is officially obsolete — Texas Instruments has ended production, and no last-time-buy window is active.
