Description
The Bel x7AH-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 1.0V to 3.3V. It is packaged in a compact, overmolded package
rated at 12A. The output is closely regulated and the efficiency of 3.3V 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.
