Warning

The worst case calculated device off time is below the minimum limit. During the power supply operation, the device might be off for longer than expected, resulting in poor output regulation at maximum load.

The device off time may be increased by decreasing the frequency or decreasing the duty cycle.  Selecting a smaller VOR would result in a smaller turn ratio and a smaller duty cycle.
