Notes

1

15µF, 35V tantalum capacitor across each output.

2

Maximum value at full load.

3

Figure is peak-to-peak.

4

Line regulation is per 1.0% change in input voltage.

5

Load regulation is for load change from 100% to 20% (see graph).

6

Standard specifications are conservative and can be optimised for specific

applications. In particular, converter start-up at lower than specified

temperature, wider input voltage range and output voltage adjustment are

all relatively simple modifications to the standard product. Consult factory

for details.

7

On dual output models the four common pins are internally connected.

The outputs can be returned through one pin while the others remain

floating.

8

Fixed frequency design provides for easier input filtering and better noise

performance.
