The output voltage is programmed by the external divider, as shown in the typical
application circuit on Page 1. Depending on the topology used, 1 or 2 output ,V
OUT
is
set as follows:
APPLICATION INFORMATION
1) Single V
OUT
First pick a value for RI that is no larger than 300K.
Too large a value of RI will reduce the AC voltage
seen by the loop comparator since the internal FB
pin capacitance can form a low pass filter with RF
in parallel with RI. The formula for RF with a given
RI and output voltage is:
R
F
= (V
OUT
/ 0.8V - 1) x (R
I
)
2) Dual V
OUT
(selectable)
First pick the lowest voltage that will be used and
utilize the same method as above.
