– PWM Block Diagram
The RSFF is reset dominant allowing both phases to go to zero duty cycle within a few tens of nanoseconds in response
to a load step decrease. Phases can overlap and go to 100% duty cycle in response to a load step increase with turn-on
gated by the clock pulses. An Error Amplifier output voltage greater than the common mode input range of the PWM
comparator results in 100% duty cycle regardless of the voltage of the PWM ramp. This arrangement guarantees the
Error Amplifier is always in control and can demand 0 to 100% duty cycle as required. It also favors response to a load
step decrease which is appropriate given the low output to input voltage ratio of most systems. The inductor current will
increase much more rapidly than decrease in response to load transients.
This control method is de
signed to provide “single cycle transient response” where the inductor current changes in
response to load transients within a single switching cycle maximizing the effectiveness of the power train and minimizing
the output capacitor requirements.
