Notes

1. For EN55022 Level B performance below -25 ºC, a 220 µF (24 VDC input), 47 µF (48 VDC input) electrolytic capacitor is required across the input of the converter.

Note:

∆

Vo is the change in the trimmed output voltage from the nominal output voltage.

Example: JTA1524S05 trimmed to 5.3 V

∆

Vo = 5.0 - 5.3 = 0.3 VDC

Vo))/

∆

Vo

The value of resistor = (5.788 - (8.25 x 0.3))/0.3 = 11.04 K

Connect the resistor between TRIM pin and -Vo pin.
