It integrates all the building blocks needed for a single-ended or push-pull converter: an oscillator, error amplifiers, a dead-time control comparator, and dual alternating outputs. Typical applications include off-line power supplies, DC-DC converters, battery chargers, and industrial power stages where a robust, proven controller core is preferred over a newer integrated switcher. ## Lifecycle and regulatory status — no obsolescence risk ## Package note — Bulk delivery For a prototype run or a low-volume repair, Bulk is convenient; for a high-volume pick-and-place line, you will want the tape-and-reel version (TL494CDBR).","metaTitle":"TL494CDB PWM Switching Controller, Active, ROHS3","metaDescription":"TL494CDB is an active PWM switching controller from Texas Instruments.
