2.10 Slope Compensation

To avoid errors associated with subharmonic oscillation as well as give noise immunity, slope compensation is used. The signal of the current ramp from the current sense was small enough that a large amount of slope compensation was needed to give the needed noise immunity to the circuit. These factors lead to 75 k Ohms being used for the RSC resistor.
