ISOLATED DC/DC CONVERTERS  
18 Vdc - 36 Vdc Input 12 Vdc /10 A, 3.3 Vdc/30 A Outputs  
0RCY-80Rxxx  
RoHS Compliant  
Rev. E  
• Isolated  
• High Efficiency  
• Low Cost  
• OCP/SCP  
• High Power Density  
• Over Temperature Protection  
• Output Voltage Trim  
• Remote On/Off

Description  
The 0RCY-80Rxxx series are isolated dc/dc converters that operate from a nominal 24 Vdc source. These units  
will provide up to 120 W of output power and 30 A of output current from a nominal 24 Vdc input. The unit is  
designed to be highly efficient and low cost. Features include remote on/off, over current protection and under-  
voltage lockout. This converter is provided in an industry standard eighth brick package.

Output Trim Equations  
Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected between  
the Trim pin and GND pin. The Trim Up resistor should be connected between the Trim pin and the Vout pin. Only  
one of the resistors should be used for any given application.
