Negative logic remote on/off Heat sink available for extended operation n n Description The CW025 Triple-Output-Series Power Modules use advanced, surface-mount technology and deliver high-quality, compact, dc-dc conversion at an economical price. Features n The CW025 Triple-Output-Series Power Modules are dc-dc converters that operate over an input voltage range of 36 Vdc to 75 Vdc and provide three outputs. These modules offer extremely low noise levels with industry-standard pinouts in a small footprint. Each highly reliable and efficient unit features remote on/off and current limit. The maximum total output power of the CW025 Triple-Output-Series Power Modules is limited to 25 W. The main output (VO1) is designed to deliver the entire 25 W. The auxiliary outputs (VO2 and VO3) can provide a total of 22.5 W, as long as the total output power does not exceed 25 W. Efficiency greater than 80%, a wide operating temperature range, and a metal case are additional features of these modules. Small size: 71.1 mm x 61.0 mm x 12.7 mm (2.80 in. x 2.40 in. x 0.50 in.)

CW025 Triple-Output-Series Power Modules: 36 Vdc to 75 Vdc Input; 25 W Data Sheet April 2008 www.DataSheet4U.com Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

Safety agency reports specify 75 V maximum input. Fusing Considerations CAUTION: This power module is not internally fused. An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow, dc fuse with a maximum rating of 5 A in series with the ungrounded input lead. Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data for further information. 2 Lineage Power Data Sheet April 2008 CW025 Triple-Output-Series Power Modules: 36 Vdc to 75 Vdc Input; 25 W www.DataSheet4U.com Electrical Specifications (continued) Table 2.
