DESCRIPTION  
The MDHU100 series power modules are 2W DC/DC converters that are specially designed to provide ultra-high levels of isolation  
(4000VAC) in a miniature DIP package. These converters operate over input voltage ranges of 4.5~5.5VDC, 10.8~13.2VDC, and  
21.6~26.4VDC. This series also has single and dual output voltages of 5, 12, 15, ±12, and ±15VDC. These converters have both medical  
(UL60601-1) and industrial (UL60950-1) safety approvals and are useful for a variety of applications including distributed power systems,  
mixed analog/digital subsystems, portable test equipment, local power networks, and battery-backed systems.  
SPECIFICATIONS: MDHU100Series  
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.
