If Pin 1 or Pin 16 is floating or tied incorrectly, the internal error amplifiers might force the feedback pin (Pin 3) to its absolute maximum limit, fully shutting down the PWM comparator. Tie unused error amplifier inputs to safe reference potentials (e.g., non-inverting to GND, inverting to REF). Share public link
Restart LTspice. The component will appear under the library directory name where you saved the symbol. Method B: Local Folder Installation (Portable) per output channel in push-pull mode, the internal
