A 240µF/200V capacitor (C2) is required for normal operation.

To meet power supply interruptions, an external circuit comprised of a capacitor (C1),

a 100

Ω/10W resistor (R1) and diode (D1) is required.

The output voltage can be adjusted by both trim and remote sense. The

maximum combined adjustment range is ±10%. Derate the maximum

output power if using the trim or sense function to increase the output

voltage.

For negative logic, if the remote on/off feature is not used, short the on/off pin to -Vin.

For positive logic, if the remote on/off feature is not used, leave the on/off pin floating.
