DESCRIPTION
LCD15 DC/DC converters provide up to 15 watts of output power in an industry standard
package and footprint. These units are specifically designed to meet the power needs of low
profile. All models feature with 2:1 wide input voltage of 9-18 VDC, 18-36 VDC and
36-75VDC, comprehensively protected against over-current, over-voltage and input
under-voltage protection conditions, and trimmable output voltage.
