Description
The SRDB-04HX20 is part of the low cost non-isolated dc/dc converter. The module uses a DIP package for
ease of layout and space savings, with a low profile of 8.5 mm. The output is closely regulated and the efficiency
of 12 V is typically 86% at full load. Features include remote sense, over current protection and remote on/off.
