Analyze transient responses, efficiency, and switching characteristics (e.g., dead time). Component Selection: Tune the oscillator resistors ( RTcap R sub cap T ) and capacitors ( CTcap C sub cap T ) for the desired operating frequency. Setting Up the TL494 LTspice Model

is a versatile Pulse-Width Modulation (PWM) control circuit widely used in switch-mode power supplies (SMPS) for its fixed-frequency operation and dual output capability. Integrating it into
