Figure 5. Error Amplier with Type III Compensation
OPERATION
Most applications demand an improved transient response
to allow a smaller output lter capacitor. To achieve a higher
bandwidth, Type III compensation is required, providing
two zeros to compensate for the double-pole response of
the output lter. Referring to Figure 5, the location of the
poles and zeros are given by:
