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.
