Feed Back Voltage Control
z
In case of output capacitance C3 is connected to Vout0, capacitance C3 connecting to Vout1 and Vout2
May be omitted.
However, if you have to care about output ripple, it is better C3 connect to each Vout1and Vout2.

This device has a capability of variable control for feed back voltage by using two input such as SP1 and SP2.
Two kind of feed back terminal exist and the following feed back control is performed.
1. Operating both Vout1 and Vout2
: Out1 is controlled by feed back terminal 1. (FB1)
No feed back operation for Out2
2. Operate Vout1 only
: Operation by feed back terminal 1 (FB1)
3. Operate Vout2 only
: Operation by feed back terminal 2 (FB2)
