The 7 V to 40 V supply range covers common industrial rails, and the 97% max duty cycle allows a buck stage to regulate down to near-zero dropout. ## Topology flexibility and output stage This controller supports buck, boost, flyback, forward, full-bridge, half-bridge, and push-pull topologies — one BOM line covers multiple power-stage designs, which simplifies inventory for a multi-product line. The two transistor-driver outputs with positive configuration drive external bipolar or MOSFET switches directly; there is no synchronous rectifier built in, so the designer adds an external SR controller if higher efficiency is the target. ## Temperature grade and package — shelf life and board fit It comes in a 16-TSSOP package (4.40 mm width) on Tape & Reel, so it feeds into a standard pick-and-place line for surface-mount assembly; store the reels dry — TSSOP bodies are moisture-sensitive and need a dry-bake before reflow if the moisture-barrier bag is breached.","metaTitle":"TL594IPWRG4 PWM Controller, 1 kHz to 300 kHz, 16-TSSOP","metaDescription":"Texas Instruments TL594IPWRG4 PWM controller with 7 V to 40 V supply, 97% max duty cycle, and industrial temp range.","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-TSSOP (0.173\\\", 4.40mm 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-TSSOP","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/TL594IPWRG4/alternatives.json"},"ai":{"faq":[{"question":"What is TL594IPWRG4's listed function on this component line?","answer":"The TL594IPWRG4 is a PWM controller with step-up, step-down, and step-up/step-down capability.
