Functional description
ST1S40
10/30
Doc ID 17928 Rev 4
Equation 6
and
Equation 7
The resistor to adjust the output voltage gives the term from output voltage to the FB pin.
GDIV(s) is:
The transfer function from FB to Vcc (output of E/A) introduces the singularities (poles and
zeroes) to stabilize the loop. Figure 5 shows the small signal model of the error amplifier
with the internal compensation network.
Figure 5.
Small signal model for the error amplifier
RC and CC introduce a pole and a zero in the open loop gain. CP does not significantly affect
system stability and can be neglected.
So GEA(s) results:
Equation 8
where GEA= Gm · Ro
The poles of this transfer function are (if Cc >> C0+CP):
