Information

This method of slope compensation is easy to implement, however, it is noise sensitive. Capacitor C1 provides AC coupling. The oscillator signal is added to the
current signal by a voltage divider consisting of resistors R1 and R2.

Figure 28. Keeps Fig numbering sequence correct
When only one output is used, this method of slope compensation can be used and it is relatively noise immune. Resistor RM and capacitor CM provide the added
slope necessary. By choosing RM and CM with a larger time constant than the switching frequency, you can assume that its charge is linear. First choose CM, then RM
can be adjusted to achieve the required slope. The diode provides a reset pulse at the ramp input at the end of every cycle. The charge current IM can be calculated
by IM = CMSe. Then RM can be calculated by RM = VCC/IM.
