Hello everyone I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge on Introduction to TL494. It supports all of the functions that are necessary for the Pulse Width Modulation (PWM) control circuits. Power supply control is the basic purpose of the TL494 device. It has an output control circuit, a flipflop, dead time comparator, two different error amplifiers, 5V reference voltage, oscillator and a PWM comparator. TL 494 operates properly between the frequency of 1kHz to 300kHz.
The Dead Time Comparator (DTC) provides around 5% of dead time. Both of the error amplifiers display a common-mode voltage from -0.3V to (Vcc-2)V. If we provide a sawtooth wave at the CT terminal and terminate RT to the referenc ...
