DESCRIPTION
The CV series consists of non-isolated DC/DC converters that can deliver up to 3A of output current in a small open
frame package. This series features remote on/off, adjustable output voltage, and efficiency up to 95%. These
converters are protected against over current, over temperature, and short circuit conditions. The CV series is RoHS
compliant and has UL60950-1, EN60950-1, and IEC60950-1 safety approvals. This series also has positive and
negative output applications as well as vertical (standard) and horizontal (“A” suffix) SIP mounting options.

NOTES
1. Output voltage programmable from 0.6V to 3.3V, 0.59V to 6.0V, 3.0V to 6.0V, and 5.0V to 15V by connecting a single resistor between the TRIM
and GND pins of the module. To calculate the value of the resistor (Rtrim) for a particular output voltage (Vo), use the equations shown in Table 1.
2. CV12S3.3-3000: When using negative output application, |Vo| trim up > 3.3V and the output current is 1.5A max.
3. CV12S3.3-3000: When Vo,set < 0.9VDC the input voltage range is 4.5 ~ 9 VDC.
4. Both vertical mounting and horizontal mounting SIP types are available. Add the suffix “A” to the model number for horizontal mounting SIP type.
5. CAUTION: This power module is not internally fused. An input line fuse must always be used.
*Due to advances in technology, specifications are subject to change without notice.
