MSKW Series  
5 Watt DC/DC Converter  
Rev A  
Single and Dual Outputs  
2:1 Wide Input Voltage Range  
FEATURES  
DESCRIPTION  
The MSKW series of DC/DC converters provide a maximum of 5 watts in a  
“gull-wing” SMT package. These converters operate over 2:1 wide input  
voltage ranges of 9-18, 18-36, or 36-75VDC. This series also has single  
output voltages of 3.3, 5, 12, and 15VDC and dual output voltages of ±5,  
±12, and ±15VDC. These converters have a typical full load efficiency of  
85%, remote ON/OFF, and continuous short circuit protection. The  
SMT Technology  
High Power Density  
Efficiency up to 85%  
1500VDC I/O Isolation  
Short Circuit Protection  
Remote ON/OFF Control  
MTBF > 1,000,000 Hours  
Industry Standard Pin-out  
2:1 Wide Input Voltage Range  
EMI Complies with EN55022 Class A  
Operating Temperature: -40°C to +71°C  
-40°C~+71°C operating temperature make these converters ideal for data  
communication equipment, mobile battery driven equipment, process/machine  
control equipment, telecommunication equipment, computer peripheral systems,  
distributed power systems, mixed analog/digital subsystems, and industrial robot systems. The  
EN55022 Class A conducted noise compliance minimizes design time, cost, and eliminates the need  
for external filter components.  
SPECIFICATIONS: MSKW Series  
All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.  
We reserve the right to change specifications based on technological advances.
