It delivers a maximum duty cycle of 97%, which means the output can stay high nearly the entire switching period — critical for low-dropout boost or buck designs where the input and output voltages are close. The controller operates from a 7 V to 40 V supply, covering 12 V, 24 V, and 36 V industrial and automotive bus rails. The 7 V minimum means it cannot run directly from a 5 V rail — a separate bias supply or a higher-voltage startup circuit is needed. ## Package and sourcing The base product number is TL594.","metaTitle":"TL594INSRG4 PWM Controller, 97% Duty Cycle, 16-SOIC","metaDescription":"Texas Instruments TL594INSRG4 PWM controller, 97% max duty cycle, 1 kHz to 300 kHz switching, 7 V to 40 V supply, -40°C to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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-SOIC (0.209\\\", 5.30mm Width)","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":"-40°C~85°C(TA)","Synchronous Rectifier":"No","Supplier Device Package":"16-SO","Voltage - Supply (Vcc/Vdd)":"7V ~ 40V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.6777","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e7f90ece3ceb8a04e3b238e384f44f54.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL594INSRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum duty cycle of TL594INSRG4?","answer":"The maximum duty cycle is 97%. This allows the output to stay high for nearly the entire switching period, which is useful in low-dropout boost or buck converters where the input and output voltages are close."},{"question":"Can TL594INSRG4 be used in a push-pull converter?","answer":"Yes. The TL594INSRG4 supports push-pull topology, along with buck, boost, flyback, forward, half-bridge, and full-bridge. The two outputs drive the primary-side switches with complementary pulses."},{"question":"What is the difference between TL594INSRG4 and TL594IN?","answer":"The TL594INSRG4 is the Tape & Reel packaged variant of the TL594IN. Both share the same die and electrical specifications — the difference is only the shipping medium: Tape & Reel for automated pick-and-place versus tube for the TL594IN."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL594INSRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL594INSRG4 when reusing this data.
