That breadth means one part number can serve multiple power stages on the same BOM — a single qualification covers isolated and non-isolated rails. It drives two external transistors (output configuration is positive, transistor-driver type) with a maximum duty cycle of 97%, leaving headroom for transformer reset in forward converters. ## Supply range and control flexibility The Vcc supply range is 7 V to 40 V, which covers standard 12 V and 24 V industrial buses without an external pre-regulator. Dead-time control and frequency control are available as on-chip features, letting you adjust overlap protection and switching period with external resistors. Clock sync is not provided, so multiple TL594CPWR controllers on the same board must be synchronised externally or run with beat-frequency management. ## Package and lifecycle status","metaTitle":"TL594CPWR PWM Controller - Texas Instruments, Active","metaDescription":"TL594CPWR from TI: PWM controller supporting buck, boost, flyback, forward, full/half-bridge, push-pull.","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)":"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-TSSOP","Voltage - Supply (Vcc/Vdd)":"7V ~ 40V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8700","priceTiers":[{"qty":1,"price":"$0.87000","currency":"USD"},{"qty":10,"price":"$0.78200","currency":"USD"},{"qty":25,"price":"$0.74200","currency":"USD"},{"qty":100,"price":"$0.60950","currency":"USD"},{"qty":250,"price":"$0.56976","currency":"USD"},{"qty":500,"price":"$0.50350","currency":"USD"},{"qty":1000,"price":"$0.39750","currency":"USD"},{"qty":2000,"price":"$0.30740","currency":"USD"},{"qty":6000,"price":"$0.30000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e7f90ece3ceb8a04e3b238e384f44f54.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL594CPWR/alternatives.json"},"ai":{"faq":[{"question":"Is TL594CPWR equivalent to TL594CN?","answer":"TL594CPWR and TL594CN share the same base die (TL594) but differ in package and temperature range.
