Description
The VRP1-20E1AC is a non-isolated dc/dc converter that operates over a wide range of input voltage (Vin = 4.5
Vdc ~ 13.8 Vdc). This unit can provide a precisely regulated output voltage from 0.591 Vdc to 5.1 Vdc and can
deliver up to 20 A of output current. This unit is designed to be highly efficient and low cost. The converter is
provided in an industry standard package.
