Note 1:
For proper measurement of V
FB
, connect OUT and FB as shown in the
Typical Operating Circuit
.
Note 2:
GPIO2, GPIO3, and GPIO4 only in the MAX6651.
Note 3:
Note that the transition must internally provide at least a hold time to bridge the undefined region (300ns max) of SCL’s
falling edge.
Note 4:
C
B
is the total capacitance of one bus line in pF. Tested with C
B
= 400pF. Rise and fall times are measured between 0.3 x
V
CC
and 0.7 x V
