Description
The SRDB-04C500 is part of the low cost non-isolated dc/dc series. The module uses a DIP package for ease
of layout and space savings, with a low profile of 8.5mm. The output is closely regulated and the efficiency is
typically 92% at full load. The unit is designed to be highly efficient and cost-effective. Features include remote
sense, output voltage adjustment and burst mode at light load.
