Manufacturer
Bel Fuse Inc.
Datasheet
Description
The xRP2-50E1A0 is a non-isolated dc/dc converter that operates over a wide range of input voltage (Vin = 5 Vdc
- 13.8 Vdc). This unit can provide a precisely regulated output voltage from 0.6 Vdc to 5.0 Vdc and can deliver
up to 50 A of output current. This unit is designed to be highly efficient and low cost. The converter is provided in
an industry standard package.
