Description
The Bel x7AH-03Hxx0 is part of the low cost non-isola ted DC/DC power converter series. It is packaged in a compact, overmolded package rated at 3A. Optional lead form ing provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. The output is closely regulated and the efficiency of 3.3V output is typically 90% at full load. Typical features include remote on/off, input under voltage lockout, over current protection and short circuit protection. Part Selection Output Voltage Input Voltage Max. Output Current Max.
