Equation 7
Equation 8
The RFB(DYN) is the dynamic resistance seen by the FB pin.
The CFB1 capacitor fixes the OLP delay and usually CFB1 results much higher than CFB.
The
Equation 5 can be still used to calculate the OLP delay time but CFB1 has to be
considered instead of CFB. Using the alternative compensation network, the designer can
satisfy, in all case, the loop stability and the enough OLP delay time alike.
