APPLICATION INFORMATION
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 voltages ,V OUT
is set as follows:
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) * (R I )
2) Dual V OUT (selectable)
First pick the lowest voltage that will be used
and utilize the same method as above.
R F = (V OUT_LOW / 0.8V - 1) * (R I ) R I ≤ 300k ?
Then use the following equation to determine
R S:
