Description

The Bel xRAH-12Fxx0 series are part of the low cost non-isolated dc/dc converter series. These converters are

available in a range of output voltages from 1.0 V to 3.3 V. It is packaged in a compact, overmolded package

rated at 12 A. The output is closely regulated and the efficiency of 3.3 V output module is typically 93% at full

load. Typical features include remote on/off, input under voltage lockout, over current protection and short circuit

protection.
