Its switching frequency is set by an external resistor and capacitor from 1kHz to 300kHz, letting you choose magnetics for size or efficiency. Each output delivers a 45% max duty cycle. The dead-time control pin lets you insert a guaranteed off-time to prevent transformer saturation during the reset interval. ## Active production — 16-SOIC package The 16-SOIC (0.154-inch width) package is a common footprint that mates with standard SOIC-16 land patterns.","metaTitle":"TL494IDR PWM Controller – Texas Instruments, 16-SOIC, Active","metaDescription":"TL494IDR PWM controller from TI, multi-topology support (buck, boost, flyback, push-pull), 1kHz~300kHz switching, 7V~40V supply, industrial temp range.","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)","Function":"Step-Up, Step-Down, Step-Up/Step-Down","Topology":"Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, Push-Pull","Clock Sync":"No","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"Dead Time Control, Frequency Control","Duty Cycle (Max)":"45%","Number of Outputs":"2","Serial Interfaces":"-","Base Product Number":"TL494","Output Configuration":"Positive","Frequency - Switching":"1kHz ~ 300kHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"No","Supplier Device Package":"16-SOIC","Voltage - Supply (Vcc/Vdd)":"7V ~ 40V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5100","priceTiers":[{"qty":1,"price":"$0.51000","currency":"USD"},{"qty":10,"price":"$0.43600","currency":"USD"},{"qty":25,"price":"$0.40640","currency":"USD"},{"qty":100,"price":"$0.32520","currency":"USD"},{"qty":250,"price":"$0.30196","currency":"USD"},{"qty":500,"price":"$0.25550","currency":"USD"},{"qty":1000,"price":"$0.19743","currency":"USD"},{"qty":2500,"price":"$0.18001","currency":"USD"},{"qty":5000,"price":"$0.16839","currency":"USD"},{"qty":12500,"price":"$0.16434","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c7861fe9c4cffdf82e84953a76a5ab14.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL494IDR/alternatives.json"},"ai":{"faq":[{"question":"Can the TL494IDR be used for a buck converter?","answer":"Yes, the TL494IDR supports buck topology as one of its listed topologies. Configure the error amplifier and dead-time control per the standard buck compensation; the 45% max duty cycle per output is sufficient for most step-down ratios at the chosen switching frequency."},{"question":"What is the closest functional second-source to the TL494IDR?","answer":"The UCC2806DWTR from TI is a comparable dual-output PWM controller with a 50% max duty cycle and similar topology support (boost, flyback, forward). It adds synchronous rectifier capability and a current-limit function, but lacks the TL494's dead-time control and has a lower switching frequency ceiling (47kHz typ).
