Description  
The 0RHW-D0Txxx series are isolated dc/dc converters that operate from a nominal 48 Vdc source. This  
converter provides up to 200 W of output power. Features include remote on/off, short circuit protection, over  
current protection, over-temperature protection, output over-voltage protection, input under-voltage protection.  
This converter is provided in an industry standard half brick package that is easy to use and provides good  
thermal performance.

CAUTION: This converter is not internally fused. An input line fuse must be used in application.  
Recommend a fast-acting fuse with maximum rating of 4A@1.2Vout or 10A@3.3Vout on system  
board. Refer to the fuse manufacture’s datasheet for further information.  
Notes: 1. This converter has internal C-L-C (0.47uF-2.2uH-4.4uF) filter.  
2. All specifications are typical at 25 C unless otherwise stated.

For 1.2V Model  
Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected the  
Trim pin, Sense(-) pin and GND pin. The Trim Up resistor should be connected the Trim pin Sense(+) pin and  
Vout pin. Only one of the resistors should be used for any given application.
