The TL494 PWM controller combines on one chip all functions required for a pulse width modulation (PWM) control circuit. This device is primarily used for power control and provides the flexibility to tailor the power control circuit for a specific application. The TL494 PWM controller 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 voltage regulator, and multiple output control circuit. The common-mode voltage range of the error amplifier is -0.3 V to VCC -2 V. The dead-time controlled comparator has a fixed offset value, providing approximately 5% dead-time. The on-chip oscillator can be bypassed by terminating RT for the reference output and providing a sawtooth input to CT, which can also drive common circuits in a synchronous multirail supply. Uncommitted output transistors provide common emitter or emitter-follower output functionality. This PWM controller provides push-pull or single-ended output operation, selectable through the output control function. The architecture of this device prohibits the possibility of either output being pulsed twice during a push-pull operation. The TL494C PWM controller can operate from 0C to 70C. The TL494I can operate from -40C to 85C. The TL494B operates from -40C to 125C. The NCV494B operates from -40C to 125C and is qualified for automotive applications.
