If the input voltage rises quickly, or the regulator output
is enabled externally, output voltage will increase to the
level set by the error amplifier output more rapidly, usually
within a couple of cycles (see Figure 6).

Normal Operation
During normal operation, switch off time is constant and
set by the COFF capacitor. Switch on time is adjusted by the
V2 control loop to maintain regulation. This results in
changes in regulator switching frequency, duty cycle, and
output ripple in response to changes in load and line. Output
voltage ripple will be determined by inductor ripple current
working into the ESR of the output capacitors (see Figures
7 and 8).
