Data Sheet  
April 2008  
DW025 Dual Output-Series Power Modules: dc-dc Converters;  
36 Vdc to 75 Vdc Input; Dual Outputs; 25 W  
Options  
n Higher-accuracy output voltage clamp set point  
n Short pins: 2.79 mm ± 0.25 mm  
(0.110 in. ± 0.010 in.)  
n Heat sink available for extended operation  
n Negative logic remote on/off  
Description  
The DW025-Series Power Modules are a family of  
dc-dc converters that operate over an input voltage  
The DW025-Series Power Modules use advanced, surface-  
range of 36 Vdc to 75 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.  
mount technology and deliver high-quality, compact, dc-dc  
conversion at an economical price.  
Features  
Each output is individually regulated by its own con-  
trol circuit and has an independent overvoltage  
clamp. With standard outputs of +3.3 V, ±5 V, ±12 V,  
and ±15 V, the DW025-Series is flexible enough to  
provide modified standard units with any combination  
of output voltages from 2 V to 15 V.  
n Small size: 71.1 mm x 61.0 mm x 12.7 mm  
(2.80 in. x 2.40 in. x 0.50 in.)  
n Low output noise  
n Industry-standard pinout  
n Metal case with separate case ground pin  
n 2:1 input voltage range  
Efficiency greater than 80%, a wide operating tem-  
perature range, and a metal case are additional fea-  
tures of these modules. They have UL, CSA, and  
VDE recognition and operate within FCC and CISPR  
Class A limits for radiated emissions.  
n Remote on/off (positive logic)  
n UL* Recognized, CSACertified, and VDE  
Licensed  
n Within FCC and CISPR Class A Radiated Limits  
n CE mark meets 73/23/EEC and 93/68/EEC  
The DW025AJ-M, BK-M, and CL-M Power Modules  
are available with common output ground pins  
(pinout A); the DW025AA-M, AB-M, AF-M, BB-M,  
and CC-M Power Modules are available with sepa-  
rate output ground pins (pinout B).  
directives  
n Two tightly regulated outputs
