11
To enable the controller, VCC must be greater than the POR
threshold; the voltage on EN must be greater than 1.23V and
VID cannot be equal to 11111. Once these conditions are
true, the controller immediately initiates a soft start
sequence.
SOFT-START
The soft-start time, t
SS
, is determined by an 11-bit counter
that increments with every pulse of the phase clock. For
example, a converter switching at 250kHz has a soft-start
time of
T
