This waveform is generated by internal oscillator and high speed comparator circuits. The internal comparator detects the voltage output and compares it to a reference voltage. This reference voltage is user-programmable and can be adjusted to provide the desired output voltage.When the output voltage is greater than the reference, a signal is sent to the internal oscillator which, in turn, adjusts the output pulse width accordingly. This process continues until the desired output voltage is achieved.ConclusionThe TL494CPWG4 is an integrated circuit used in various DC/DC switched-mode power supplies. It is part of the TL494 family of voltage regulator ICs and works by generating a pulse-width modulated waveform which regulates the output voltage in the presence of varying loads.
