... Note: The loading output voltage will not exceed the power supply’s maximum output voltage, even if set above this maximum voltage. The example above applies only when setting below the maximum output voltage. Maximum output voltage for the power supply can be output by opening the loading input pin (19 pin). 284 = 8V) CC BA5931FP ...
