DESCRIPTION
0.86 x 0.37 x 0.44 inches
21.8 x 9.3 x 11.2 mm
The DCMCU2 series of DC/DC power converters consists of fully regulated single and dual
output models with 4:1 ultra wide input voltage ranges of 4.5-18 VDC, 9-36 VDC, and 18-75
VDC. These converters provide 2 Watts of output power in a very small SIP-8 package
occupying only 0.32 square inches on the PCB. An excellent efficiency allows an operating
temperature range up to +75°C at full load without derating. Further features include 1500VDC
I/O isolation, remote on/off control, and short circuit protection. These converters are RoHS
compliant and have CSA/UL/IEC/EN 60950-1 safety approvals. These converters’ very
compact dimensions make them an ideal solution for many space critical applications in
battery powered instrumentations.
