Description
The CC025 Dual-Output-Series Power Modules are dc-dc converters that operate over an input voltage range
of 18 Vdc to 36 Vdc and provide two regulated outputs. These modules offer low noise levels with industry-
standard pinouts in a small footprint. Each highly reliable and efficient unit features remote on/off and current
limit.
Each output is individually regulated by its own control circuit and has an independent overvoltage clamp. With
standard outputs of ±5 V, ±12 V, and ±15 V, the CC025 Dual-Output-Series is flexible enough to provide modi-
fied standard units with any combination of output voltages from 2 V to 15 V.

Absolute Maximum Ratings
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 operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.

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 (see Safety Considerations section).
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.
