DESCRIPTION
The LANCW15 series of DC/DC power converters provides 15 watts of output power in a 1.25 x 0.80 x 0.40 inch DIP
package. This series has single and dual output models with 2:1 wide input voltage ranges of 9-18VDC, 18-36VDC, and
36-75VDC. Some features include high efficiency, 1600VDC I/O isolation, six-sided shielding, and positive logic remote
ON/OFF. These converters are also protected against over voltage (single outputs only), over load, and short circuit
conditions. All models are RoHS compliant and have UL60950-1, EN60950-1, and IEC60950-1 safety approvals. This
series is best suited for use in wireless networks, telecom/datacom, measurement equipment, industry control systems, and
semiconductor equipment.

MIL-HDBK-217F Notice2 @Ta=25°C, Full load (Ground, Benign, controlled environment).
2. Maximum value at nominal input voltage and full load.
3. Typical value at nominal input voltage and no load.
4. Typical value at nominal input voltage and full load.
5. Test by minimum Vin and constant resistive load.
6. Ripple and Noise is measured with a 1µF ceramic capacitor in parallel with the output pins.
7. The ON/OFF control pin voltage is referenced to -Vin.
8. The LANCW15 series can meet EN55022 Class B with an external filter on the input pins to the converter. The filter capacitor suggested is TBD.
9. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter capacitor suggested is TBD.
