This topology saves board space and reduces BOM count compared to a discrete boost plus separate LDO — the boost pre-regulates the rail feeding the LDO, so the LDO sees a clean input even when the battery or intermediate bus sags. ## Input range and output current ceiling The supply voltage spans 4.5V to 20V, covering common Li-ion battery stacks (2S–5S) and 12V/24V industrial rails. Output 1 is rated at 2.4A — that is the boost converter's peak switch current, so the actual output current depends on the input-to-output voltage ratio and inductor selection. Output 2 is programmable, giving flexibility for a secondary rail that the LDO regulates down from the boost output. Switching frequency is selectable at 500 kHz or 1 MHz. The higher frequency shrinks the inductor footprint but increases switching losses; the lower frequency improves efficiency at heavy loads. Texas Instruments has not issued a last-time-buy notice or end-of-life notification for this base product number.","metaTitle":"TPS65235-1RUKT Texas Instruments PMIC – Boost + LDO","metaDescription":"Texas Instruments TPS65235-1RUKT PMIC: boost converter plus LDO in 20-WQFN. 4.5V-20V input, 2.4A output 1, programmable output 2.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost) (1), Linear (LDO) (1)","w/Sequencer":"No","w/LED Driver":"No","w/Supervisor":"No","Mounting Type":"Surface Mount","Package / Case":"20-WFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 20V","Number of Outputs":"2","Base Product Number":"TPS65235","Frequency - Switching":"500kHz, 1MHz","Operating Temperature":"-40°C~85°C","Supplier Device Package":"20-WQFN (3x3)","Voltage/Current - Output 1":"2.4A","Voltage/Current - Output 2":"Programmable","Voltage/Current - Output 3":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5500","priceTiers":[{"qty":1,"price":"$2.55000","currency":"USD"},{"qty":10,"price":"$2.28700","currency":"USD"},{"qty":25,"price":"$2.15720","currency":"USD"},{"qty":100,"price":"$1.83780","currency":"USD"},{"qty":250,"price":"$1.72568","currency":"USD"},{"qty":500,"price":"$1.50996","currency":"USD"},{"qty":1250,"price":"$1.25112","currency":"USD"},{"qty":2500,"price":"$1.22100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/89d73045b0c0fbd2752a1fc54ac037fe.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65235-1RUKT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS65235-1RUKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS65235-1RUKT when reusing this data.
