Output Voltage Trimming (optional)
After setting the output voltage from the procedure above the output
may be margined down (26Vf min) by a resistor from SC-SG using this
formula:

Where V
fd
is the desired factorized bus and V
fs
is the set factorized bus.
A low voltage source can be applied to the SC port to margin the load
voltage in proportion to the SC reference voltage.
An external capacitor can be added to the SC port as shown in Figure 16
to control the output voltage slew rate for soft start.
