(initial conditions) command to set voltages on capacitors like the timing capacitor ( cap C sub cap T tl494 ltspice
: A typical TL494 subcircuit includes internal components like two error amplifiers, a sawtooth oscillator, a dead-time control (DTC) comparator, and output steering flip-flops. How to Integrate TL494 into LTspice a sawtooth oscillator
The approximate frequency is given by: $$f_osc \approx \frac1.1R_T \cdot C_T$$ In LTspice, this is modeled using a current source charging a capacitor, with a Schmitt trigger to reset the capacitor once the voltage threshold is reached. a dead-time control (DTC) comparator
This pin dictates the output topology:
