NettetLTspice modeling can be used to measure control loop gain and phase, thus producing Bode plots for LED drivers. The accuracy of the LTspice simulation data is dependent on the accuracy of the SPICE models used, though carefully modeling each component to account for real-world behavior comes at the cost of increased simulation times.
