It provides a single output phase driving external transistors. Housed in a 16-pin DIP package, it operates from a supply voltage of 7 V to 40 V and switches between 1 kHz and 300 kHz. The maximum duty cycle of 97% allows near-continuous on-time, useful for low-dropout step-down regulation. Control features include dead-time control and frequency control, giving the designer flexibility to adjust the output waveform and switching frequency for the specific topology. This means the manufacturer no longer produces the part and has no scheduled last-time-buy window. New designs should not use this part; for legacy BOM support, the only sourcing channel is independent distribution or surplus inventory. It is not specified for industrial or automotive temperature ranges.","metaTitle":"TL594CN PWM Controller – Texas Instruments, Obsolete, 16-DIP","metaDescription":"TL594CN is an obsolete Texas Instruments PWM controller in a 16-DIP package.

The TL594 (without the 'CN' suffix) is the base product number, but its lifecycle status and package options should be verified independently. For a drop-in substitute, check the TL594 family datasheet for pin-compatible variants; many share the same 16-DIP footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL594CN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL594CN when reusing this data.
