Fairchild TL494 SMPS Controller Datasheet
The TL494 is a PWM controller for switching regulators, featuring an internal 5 V reference, uncommitted output driver, error amplifiers, and an on‑chip oscillator that can operate in master or slave mode. It supports variable duty‑cycle control from 1 kHz to 300 kHz and can drive push‑pull or single‑ended topologies.
The datasheet lists absolute maximum ratings, electrical characteristics, mechanical dimensions for 16‑DIP and 16‑SOP packages, ordering information, and a life‑support policy disclaimer. A typical step‑down converter application circuit is also shown.
