10. Setting The Output Voltage
The output voltage can be set to an arbitrary value by the ratio of the feedback resistance to -INE1 (-INE2).
■Set the output voltage to a value higher than the reference voltage (1 V) of the Error Amp.
■Under usage conditions where the duty cycle is 30 or less, set V_O1 < V_O2 as much as possible.
