Load Transients

When the load increases suddenly, the output voltage immediately drops. This voltage drop is reflected as a rising voltage on the DROOP pin. This rising voltage forces the PWM to pulse sooner and more frequently, which causes the inductor current to rapidly increase. As the inductor current reaches the new load current, a steady-state operating condition is reached and the PWM switching resumes the steady-state frequency. Similarly, when the load releases suddenly, the output voltage rises. This rise is reflected as a falling voltage on the DROOP pin. This rising voltage forces a delay in the PWM pulses until the inductor current reaches the new load current, when the switching resumes and steady-state switching continues.

For simplicity, neither Figure 11 or Figure 12 show the ripple on the output VCORE nor the DROOP waveform.
