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 (R

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.
