RT3612EB provides a new generation of dual ramp

mechanism to enhance performance. Except original ramp

to minimize jitter, additional Advanced Ramp is developed

to solve loop natural lag due to PCB parasitic inductance

and prevent adjacent PWM turn-on. That has current signal

meaning and prediction. The transient ring-back can be

effectively suppressed. Figure 18 and Figure 19 show the

apparent difference between single ramp and dual ramp

with PCB parasitic inductance condition.
