No synchronous rectifier drive or clock sync is built in — this is a straightforward PWM core for isolated and non-isolated designs where you handle the SR externally. ## Switching frequency range — transformer sizing The 1 kHz to 300 kHz range lets you trade off transformer size against core losses. At the low end you use a larger magnetics but get lower switching losses; at the high end you shrink the transformer but need faster diodes and careful layout. The TL494CPWR gives you the flexibility to pick the sweet spot for your power level and cost target.","metaTitle":"TL494CPWR PWM Controller, 1 kHz–300 kHz, 16-TSSOP","metaDescription":"TL494CPWR is an active PWM controller from TI supporting buck, boost, flyback, and bridge topologies.","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-TSSOP (0.173\\\", 4.40mm 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":"0°C~70°C(TA)","Synchronous Rectifier":"No","Supplier Device Package":"16-TSSOP","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":"$0.43700","currency":"USD"},{"qty":25,"price":"$0.40800","currency":"USD"},{"qty":100,"price":"$0.32650","currency":"USD"},{"qty":250,"price":"$0.30316","currency":"USD"},{"qty":500,"price":"$0.25652","currency":"USD"},{"qty":1000,"price":"$0.19822","currency":"USD"},{"qty":2000,"price":"$0.18073","currency":"USD"},{"qty":6000,"price":"$0.16907","currency":"USD"},{"qty":10000,"price":"$0.16500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c7861fe9c4cffdf82e84953a76a5ab14.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL494CPWR/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum duty cycle of TL494CPWR?","answer":"For push-pull or half-bridge topologies, the two outputs together give a combined 90% on-time per cycle."},{"question":"Is TL494CPWR equivalent to TL494CN?","answer":"TL494CPWR and TL494CN share the same base PWM controller function, but TL494CPWR is in a 16-TSSOP surface-mount package while TL494CN is in a 16-PDIP through-hole package.
