VIPer53 - E Transconductance error amplifier
27/36
The lowest load gives another condition for stability: The frequency F
BW1
must not encounter
the second order slope generated by the load pole and the integrator part of the error
amplifier. This condition can be met by adjusting the C
COMP
value:
Equation 13
The above formula gives a minimum value for C
COMP
. It can be then increased to provide a
natural soft start function as this capacitor is charged by the error amplifier current capacity
