DESCRIPTION

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 volt-

ages of 5 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.

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.

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.
