This makes the part a fit for handheld and mobile devices where the input voltage drops as the battery discharges. ## 10 µA quiescent current — standby power budget At 10 µA supply current, the converter draws negligible current in light-load or shutdown modes. For battery-powered equipment that spends most of its life in standby, this figure directly sets the sleep-mode power budget.","metaTitle":"TPS61121PWRG4 DC-DC Converter, 1.8V-5.5V, 10µA Iq, 16-TSSOP","metaDescription":"Texas Instruments TPS61121PWRG4 DC-DC converter, 1.8V to 5.5V input, 10µA supply current, -40°C to 85°C, 16-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Applications":"Handheld/Mobile Devices","Mounting Type":"Surface Mount","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Supply":"10µA","Voltage - Supply":"1.8V ~ 5.5V","Base Product Number":"TPS611","Operating Temperature":"-40°C~85°C","Supplier Device Package":"16-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/995ae754a2ec387b6971db743945fed9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61121PWRG4/alternatives.json"},"ai":{"faq":[{"question":"What applications is TPS61121PWRG4 intended for?","answer":"The part is listed for Handheld/Mobile Devices — battery-powered portable equipment where wide input range and low quiescent current are critical."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61121PWRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61121PWRG4 when reusing this data.
