摘要：
A ramp generator is provided to provide a multi-slope ramp signal for a PWM power converter. The ramp generator determines the slope turning points for the multi-slope ramp signal according to the error signal of the PWM power converter and thereby improve the transient response of the PWM power converter. Preferably, the slope turning point of the multi-slope ramp signal varies with the average of the error signal and is thus adaptive to the error signal and thereby the load condition.
