3 Description

The TL494 device incorporates all the functions

required in the construction of a pulse-widthmodulation

(PWM) control circuit on a single chip.

Designed primarily for power-supply control, this

device offers 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 singleended

output operation, which can be selected

through the output-control function. The architecture

of this device prohibits the possibility of either output

being pulsed twice during push-pull operation.

The TL494 device is characterized for operation from

0°C to 70°C. The TL494I device is characterized for

operation from –40°C to 85°C.
