It operates from a 7 V to 40 V supply rail and switches from 1 kHz to 300 kHz, covering applications from line-frequency converters to compact magnetics designs. The controller supports buck, boost, flyback, forward converter, half-bridge, full-bridge, and push-pull topologies, making it a single-component solution for many SMPS architectures. ## 97 % duty cycle and dual outputs A maximum duty cycle of 97 % allows near-continuous on-time, which is critical for boost and flyback designs that need high step-up ratios. The two transistor-driver outputs can be paralleled for higher current or configured for push-pull and bridge topologies. Control features include dead-time control and frequency control, giving the designer fine adjustment of the output waveform and switching losses. ## Through-hole package and commercial temperature grade Housed in a 16-pin PDIP (0.300-inch, 7.62 mm pitch), the TL594CNG4 is a through-hole part suited for prototyping, low-volume production, and designs where hand-assembly or rework is expected.","metaTitle":"TL594CNG4 PWM Controller, 7 V to 40 V, 97 % Duty Cycle","metaDescription":"Texas Instruments TL594CNG4 PWM controller, 7 V to 40 V supply, 1 kHz to 300 kHz switching, 97 % max duty cycle.","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":"Tube","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":"Through Hole","Output Phases":"1","Package / Case":"16-DIP (0.300\\\", 7.62mm)","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-PDIP","Voltage - Supply (Vcc/Vdd)":"7V ~ 40V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e7f90ece3ceb8a04e3b238e384f44f54.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL594CNG4/alternatives.json"},"ai":{"faq":[{"question":"Can TL594CNG4 be used in push-pull topology?","answer":"Yes, the TL594CNG4 supports push-pull topology as one of its listed topologies, along with buck, boost, flyback, forward converter, half-bridge, and full-bridge."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL594CNG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL594CNG4 when reusing this data.
