DESCRIPTION
The LANCUW8 series of DC/DC power converters provides 8 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 4:1 wide input voltage ranges of 9-36VDC, 18-75VDC, and
43-160VDC. Some features include high efficiency up to 88%, 1600VDC I/O isolation, five-sided shielding, remote
ON/OFF control, and no minimum load requirement. 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,
IEC60950-1, and EN50155 safety approvals (pending). This series is best suited for use in wireless networks,
telecom/datacom, measurement equipment, industry control systems, semiconductor equipment, and railway systems.

NOTES
1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C.
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. The ON/OFF control pin voltage is referenced to -Vin.
7. Operating Ambient Temperature:
Converters can meet the railway T2 and TX temperature requirements.
T2: -40°C to +70°C for all models, TX: -40°C to +85°C with power derating to 55% output power.
8. The LANCUW8 series can meet EN55022 and EN55011 Class A with an external capacitor on the input pins to the converter.
Recommended: 24Vin Models: 1µF/50V 1210 MLCC
48Vin Models: 0.47µF/100V 1812 MLCC
110Vin Models: 1µF/250V*2pcs 1812 MLCC
9. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5.
Recommended: 24Vin & 48Vin Models: Nippon chemi-con KY series, 220µF/100V
110Vin Models: Nippon chemi-con KXJ series, 150µF/200V
10. For surface mount (SMT) type add the suffix “S” to the model number. Ex: LANC2405UW8S.
11.
CAUTION:
This power module is not internally fused. An input line fuse must always be used.
