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 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.  
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.
