Description
The S7DB-12C1AH is part of the low cost non-isolated DC/DC power converter series. The module uses a DIP
package for ease of layout and space savings, with a low profile of 8.5mm. The output is widely trimmed from
0.9V to 2.5V, and the efficiency of 2.5V output module is typically 92% at full load. Features include remote
sense, remote on/off, short circuit protection, over current protection and input under-voltage lockout.
