If you need a power-supply control device which has all the functions of Pulse-Width-Modulation control circuit in aTL494 PWM Operational Test Circuit Diagram and Waveforms single chip, you may consider the TL494 PWM control circuit. Below we provide you with its Operational Test Circuit Diagram, Waveforms and the datasheet.

According to the datasheet, the Texas Instruments TL494 offers the flexibility to tailor the power supply control circuitry to a specific application. This device contains two error amplifiers (exhibit common mode voltage range of -0.3V to Vcc -2V), a DTC comparator, a pulse steering control flip-flop, a 5V 5%-precision regulator, and output control circuits. You can see the waveform of TL494 PWM test circuit of voltage (voltage waveform) at C1, C2, CT, DTC 0 V, and Feedback 0.7 V, click picture to enlarge.

Another features of TL494 PWM control circuits are Uncommitted Outputs for 200-mA Sink or Source Current, Output Control Selects Single-Ended or Push-Pull Operation, Internal Circuitry Prohibits Double Pulse at Either Output, Circuit Architecture Allows Easy Synchronization and more.

With kind of such those architecture, TL494 prohibits the possibility of either output being pulsed twice during push-pull operation since it provide either common-emitter or emitter-follower output capability. Complete description of Texas Instrument TL494 Operational Test Circuit Diagram and Waveforms can be found here in the TL494 datasheet (source: ti.com).
