It drives a single transistor output at switching frequencies up to 500 kHz and delivers a maximum duty cycle of 96%, which is critical for flyback designs that need wide output regulation range without pulse skipping. Operating from a 10 V to 30 V supply rail, the controller suits industrial power supplies fed from a regulated auxiliary bus or a loosely regulated bulk rail. The tube packaging is typical for engineering samples and low-volume production runs; for higher volumes, verify the reel option with your sourcing desk.","metaTitle":"Texas Instruments TL2842BD-8 PWM Controller, Boost/Flyback","metaDescription":"TL2842BD-8 PWM controller from TI, boost/flyback/forward topology, up to 500kHz switching, 96% duty cycle, 10-30V supply, -40 to 85°C, SOIC-8, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Function":"Step-Up, Step-Up/Step-Down","Topology":"Boost, Flyback, Forward","Clock Sync":"No","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Control Features":"Frequency Control","Duty Cycle (Max)":"96%","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"Up to 500kHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"No","Supplier Device Package":"8-SOIC","Voltage - Supply (Vcc/Vdd)":"10V ~ 30V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.34","priceTiers":[{"qty":1,"price":"$1.34000","currency":"USD"},{"qty":10,"price":"$1.20100","currency":"USD"},{"qty":25,"price":"$1.13960","currency":"USD"},{"qty":100,"price":"$0.93620","currency":"USD"},{"qty":250,"price":"$0.87512","currency":"USD"},{"qty":500,"price":"$0.77338","currency":"USD"},{"qty":1000,"price":"$0.61056","currency":"USD"},{"qty":2500,"price":"$0.57600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f450aa6242c0dd363ceebc87ffbffd81.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL2842BD-8/alternatives.json"},"ai":{"faq":[{"question":"What is TL2842BD-8's listed function and topology?","answer":"The controller supports step-up and step-up/step-down functions with boost, flyback, and forward topologies.
