It operates from a 7V to 40V supply rail and switches from 1kHz to 300kHz, with a maximum duty cycle of 45% per output. No official successor is recorded; the TL494 family includes many active variants, but none is a direct drop-in replacement without verifying pinout and package.","metaTitle":"TL494CDBR PWM Controller, Obsolete, Sourced to Order","metaDescription":"TL494CDBR is an obsolete PWM controller from TI, 7V-40V supply, 1kHz-300kHz switching, 16-SSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","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-SSOP (0.209\\\", 5.30mm Width)","Product Status":"Obsolete","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-SSOP","Voltage - Supply (Vcc/Vdd)":"7V ~ 40V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c7861fe9c4cffdf82e84953a76a5ab14.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL494CDBR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TL494CDBR?","answer":"No official replacement is listed by the manufacturer. The TL494 family includes many active variants (e.g., TL494CN in PDIP-16, TL494CD in SOIC-16), but each must be checked for pin compatibility and package fit. The TL494CDBR uses a 16-SSOP package, which is less common than the SOIC-16 version."},{"question":"What is the function of TL494CDBR?","answer":"It is a PWM controller designed for a wide range of DC-DC converter topologies: buck, boost, flyback, forward, half-bridge, full-bridge, and push-pull.
