| NON-ISOLATED DC/DC CONVERTER 3.3V Input 0.9V to 2.5V/12A Output S7DB-12C1AH * * * * Non-Isolated Fixed frequency (300kHz) Low profile package (8.5mm) Remote Sense * * * * Remote On/Off (Active High Logic) Input Under-voltage Lockout (UVLO) OCP/SCP Wide Trim Output 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. Part Selection Output Voltage 0.9 - 2.5V Input Voltage 3.3V Max. Output Current 12A Max. Output Power 30W Typical Efficiency 92% Model Number S7DB-12C1AH Note: Add "R" suffix at the end of the model number to indicate "Reel Packaging", and "G" for "Tray Packaging".
