TL494CN PWM Regulator Circuit Original TI DIP-16

. TI DIP-16 40V, 0.2A 300KHz PWM regulator TL494CN PWM circuit. New original circuits from the manufacturer TEXAS INSTRUMENTS. The photo shows the product being sold.. The TL494 chip contains all the functions required to build a pulse width modulation (PWM) control circuit on a single chip. Designed primarily for power control, this device offers the flexibility to customize power control circuits for a specific application. The TL494 device includes two error amplifiers, an adjustable on-chip oscillator, a dead-time control (DTC) comparator, a pulse control flip-flop, a 5% precision 5-V regulator and output control circuitry . The error amplifiers show a common-mode voltage range of -0.3 V to VCC - 2 V. The dead-time control comparator has a fixed offset that provides about 5% dead time. The built-in oscillator can be bypassed by connecting RT to the reference output and providing a sawtooth input to CT, or it can control common-mode circuits in synchronous multi-rail power supplies. Uncommitted output transistors provide output with a common emitter or with an emitter secondary. The TL494 chip provides either a push-pull output or a single-ended output, which can be selected using the output control function. The architecture of this circuit excludes the possibility of any of the outputs pulsing twice during a reciprocal operation. The TL494 chip features operation from 0°C to 70°C.
