Maximum duty cycle is 97 %. Supply range is 7 V to 40 V. Two totem-pole transistor-driver outputs handle external MOSFETs or bipolar switches directly. ## Dead time control and frequency setting — what to watch Dead time is adjustable via a pin, which means you can program overlap protection for half-bridge and push-pull stages without adding external logic. Frequency is set by an external RT and CT — no internal oscillator trim, so keep the RC tolerance in your BOM budget if tight regulation matters. The controller lacks clock sync, so if you are paralleling multiple converters, expect beat frequencies unless you slave them to a master timing signal externally. It belongs in indoor power supplies, telecom rectifiers, office equipment, and appliance PSUs.","metaTitle":"TL594CDR PWM Controller, 1 kHz–300 kHz, 97% Duty Cycle","metaDescription":"TL594CDR is an active PWM controller IC 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-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Control Features":"Dead Time Control, Frequency Control","Duty Cycle (Max)":"97%","Number of Outputs":"2","Serial Interfaces":"-","Base Product Number":"TL594","Output Configuration":"Positive","Frequency - Switching":"1kHz ~ 300kHz","Operating Temperature":"0°C~70°C(TA)","Synchronous Rectifier":"No","Supplier Device Package":"16-SOIC","Voltage - Supply (Vcc/Vdd)":"7V ~ 40V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9500","priceTiers":[{"qty":1,"price":"$0.95000","currency":"USD"},{"qty":10,"price":"$0.85400","currency":"USD"},{"qty":25,"price":"$0.81040","currency":"USD"},{"qty":100,"price":"$0.66560","currency":"USD"},{"qty":250,"price":"$0.62216","currency":"USD"},{"qty":500,"price":"$0.54982","currency":"USD"},{"qty":1000,"price":"$0.43407","currency":"USD"},{"qty":2500,"price":"$0.40950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e7f90ece3ceb8a04e3b238e384f44f54.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL594CDR/alternatives.json"},"ai":{"faq":[{"question":"Is TL594CDR obsolete?","answer":"No — TL594CDR is listed as Active by Texas Instruments.
