Notes

1. No one converter may carry more than its maximum rated current.

2. Individual converter operation, load and layout may affect the actual current shared. Contact Applications Engineering for more

information powerapps@crane-eg.com.

3. When paralleling SMFLs a diode is required at the input of each inhibit pin as SMFLs do not have an internal diode on the inhibit pin.
