Equation 2
Equation 3
where:
Equation 4
Sn represents the slope of the sensed inductor current, Se the slope of the external ramp
(VPP peak-to-peak amplitude) that implements the slope compensation to avoid sub-
harmonic oscillations at duty cycle over 50%.
The sampling effect contribution FH(s) is:
Equation 5
where:
Equation 6
and
Equation 7

Error amplifier compensation network
The ST1CC40 device embeds the error amplifier (see Figure 6) and a pre-defined
compensation network which is effective in stabilizing the system in most of the application
conditions.
