APPLICATION INFORMATION
loop-gain compensation (continued)
To achieve fast transient response and the better output voltage regulation, a compensation circuit is added to
improve the feedback control. The whole system is shown:

To PWM
This circuit is composed of one integrator, two poles, and two zeros:
Assuming R1 << R2 and C2 << C3, the equation is:
