Description
The xRP4-80E1A0 is a non-isolated dc/dc converter that operates from a nominal 12 V source. This unit can
provide a precisely regulated output voltage from 0.8375 Vdc to 5.0 Vdc and can deliver up to 80 A of output
current. This unit is designed to be highly efficient and low cost. The converter is provided in an industry
standard package.
