Description
The Bel x7AH-01Cxx0 is part of the low cost non-isolated dc/dc converter series. The modules use a SMD or
SIP package or vertical package for ease of layout and space savings. The output is closely regulated and the
efficiency of 12 V output module is typically 86% at full load. Typical features include allows burst mode
operation at low load currents and trim function (option).
