8.3.1.1 On-Time Modulator
The input voltage feedforward modulator converts the integrated current error signal, ILerr, into an inductor on time that provides a controlled volt-second balance across the inductor over each full switching period that simplifies the current error integration loop design. The modulator produces a full-cycle averaged small signal Vcntrl to dIL/dt transfer function given by Equation 1:
Equation 1. 
Thus, the inductor current modulator gain is given by Equation 2:
Equation 2. 
This natural integration 1/f function allows the current loop to be compensated by the mid-band gain of the error current integrator. Use L = 0.22 μH for calculation.
