The buck output adjusts from 1.1V to 20V; the LDO covers 1.1V to 5.5V. Input supply range is 3V to 36V, and the switching frequency is programmable from 100kHz to 2.5MHz — useful for synchronising with the system clock or avoiding sensitive frequency bands. ## Automotive-grade and temperature range The supervisor output (w/Supervisor = Yes) adds a reset or power-good signal, which simplifies sequencing in an ECU or motor-drive controller.","metaTitle":"TPS65321QPWPRQ1 Automotive PMIC, Buck + LDO, NRND","metaDescription":"Texas Instruments TPS65321QPWPRQ1 dual-output PMIC: 3.2A buck + 280mA LDO, AEC-Q100, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100, Eco-Mode™","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Down (Buck) (1), Linear (LDO) (1)","w/Sequencer":"No","w/LED Driver":"No","w/Supervisor":"Yes","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","Product Status":"Not For New Designs","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 36V","Number of Outputs":"2","Base Product Number":"TPS65321","Frequency - Switching":"100kHz ~ 2.5MHz","Operating Temperature":"-40°C~125°C","Supplier Device Package":"14-HTSSOP","Voltage/Current - Output 1":"1.1V ~ 20V, 3.2A","Voltage/Current - Output 2":"1.1V ~ 5.5V, 280mA","Voltage/Current - Output 3":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/640092f8e277d47a208cccaf76b54609.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65321QPWPRQ1/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does TI provide for TPS65321QPWPRQ1?","answer":"The evidence does not list specific compliance certificates (RoHS, REACH, UL, IEC).
