It operates from a 7 V to 40 V supply rail and switches from 1 kHz up to 300 kHz, covering most offline and intermediate-bus designs. Two open-collector transistor-driver outputs deliver up to 97 % duty cycle, which is useful for high step-down ratio buck converters or push-pull stages where maximum on-time is needed. ## Topology flexibility and control features The part supports buck, boost, flyback, forward converter, full-bridge, half-bridge, and push-pull topologies — a single BOM line that covers multiple power-stage architectures. Dead-time control and frequency control pins let the designer adjust the output pulse timing and switching frequency independently, which is critical for avoiding transformer saturation in push-pull and half-bridge stages.","metaTitle":"TL594CNSR PWM Controller, 7V-40V Supply, 1kHz-300kHz","metaDescription":"TL594CNSR PWM controller from TI. 2 outputs, 97% duty cycle, 7V-40V supply.

Both share the same core PWM controller function, supply range, and switching frequency. The difference is the package suffix — the NSR suffix indicates Tape & Reel packaging, while the CD suffix typically ships in tubes or reels depending on the order code. Functionally they are interchangeable; the choice depends on your assembly line's preferred reel format."},{"question":"Can TL594CNSR be used for a buck converter?","answer":"Yes. The TL594CNSR supports buck topology directly. With two outputs and a 97 % max duty cycle, it can drive a single-ended buck stage or a synchronous buck with external driver logic."},{"question":"Is TL594CNSR RoHS compliant?","answer":"Confirm the specific date-code compliance certificate with your supplier at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL594CNSR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL594CNSR when reusing this data.
