DESCRIPTION

Figure 1 shows a standard connection scheme for a dual output

model. Users may also elect to use a dual output device to provide

a single output at double the rated output voltage. The double

voltage connection is achieved by leaving the normal output

common pin (Pin 15) unconnected and using either the positive or

negative Vout pin for the output common connection.

The DCH Series™ offers isolated, unregulated DC/DC converters

with up to 3 watts of output power in a low profile (0.350 max.) metal

package. Single and dual output models are available with input

voltages of 5, 12, or 28 VDC. DCH Series converters operate over

a –55°C to +100°C temperature range.

DCH Series converters use a non-saturating core circuit operating

at a frequency of approximately 100 kHz, which reduces reflected

input ripple and minimizes EMI/RFI problems. For applications

requiring MIL-STD-461C, CEO3, reflected input ripple levels, refer

to Section B5 or contact your Interpoint representative for matching

EMI filters.

On all DCH Series models, a tantalum capacitor with a minimum

value of 22 µF and an appropriate voltage rating should be

connected between the output common and the output line(s) to

minimize output ripple.

Notes

1. Nominal output voltage is correct only for nominal input voltage. Output voltage changes in proportion to input voltage.

2. Output ripple results require the connection of a tantalum capacitor (22 µF minimum) across each output.
