APPLICATION INFORMATION
Setting the Output Voltages
Set the output voltage on each output by
selecting the resistive voltage divider ratio. The
voltage divider drops the output voltage to the
feedback threshold voltage. Use 10k
to 50k
for the low-side resistor of the voltage divider.
For the step-up converter, determine the
high-side resistor R1 by the equation:
