• High Efficiency
• Low Profile Package
• Trim Function (option)
• Allows Burst Mode Operation
at Low Load Currents
Description
The Bel x7AH-01Fxx0 is part of the low cost non-isolated dc/dc converter series. The modules use a surface
mount 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 88% at full load. Typical features include burst mode operation
at light load and trim function (option).
