Description
The Bel SRDB-30B1AH is part of the non-isolated dc/dc converter Power Module series. The modules use a
DIP package for ease of layout and space savings. The output can be trimmed from 0.9 V to 2.75 V and the
efficiency of 2.5 V output module is typically 93% at full load. Typical features include remote on/off, over
current protection and short circuit protection.
