Description
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 out-
put 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.

Absolute Maximum Ratings
Data Sheet
April 2008
www.DataSheet4U.com
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute 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.

* Operation is specified to 75 V, provided the minimum load on Output 1 is at least 0.75 A. 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 fus-
ing 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.
