tBOOT

Skip mode after output reaches the

regulation voltage or PWM mode; measured

at FB with respect to the voltage target set

by the VID code (see Table 4)

Soft-start, soft-shutdown, skip mode, and

output has not reached the regulation

voltage; measured at FB

Measured at FB with respect to the voltage

target set by the VID code (see Table 4)

Measured from the time when FB reaches

the boot target voltage (Note 2)
