Description
The tl494 device incorporated all the functions required in the construction of a pulse-width-modulation (pwm) control circuit on a single chip. Designed primarily for power-supply control, this device offerers the flexibility to tailor the power-supply control circuitry to a specific application.
The TL494 device contains two error amplifiers, an on-chip adjustable oscillator, a dead-time control (DTC) comparator, a pulse-steering control flip-flop, a 5-V, 5%-precision regulator, and output-control circuits.
The error amplifiers exhibit a common-mode voltage range from 0.3 v to vcc 2 v. The dead-time control comparator has a fixed offset that provides approximately 5% dead time. The on-chip oscillator can be bypassed by terminating rt to the reference output and providing a sawtooth input to ct, or it can drive the common circuits in synchronous multiple-rail power supplies.
The uncommitted output transistors provide either common-emitter or emitter-follower output capability. The tl494 device provides for push-pull or single-ended output operation, which can be selected through the output-control function. The architecture of this device prohibits the possibility of either output being pulsted twice during push-pull operation.
The tl494c device is characterized for operation from 0°C to 70.°- c. The tl494i device is characterized for operation from 40°C to 85.°-
