3S8W_1209S3RP – GAPTEC

The 3S8W_1209S3RP is a compact, isolated DC-DC converter module designed for embedded systems requiring a regulated 9V output from a wide 9V to 18V input voltage range (2:1 input ratio). This module delivers a single, tightly regulated 9V output at a maximum current of 333mA, providing a power output of 1W. Employing a robust switching topology, the converter achieves a typical efficiency of 81% across the input voltage range. The isolation barrier provides electrical isolation between the input and output, enhancing safety and reducing ground loop issues. The module is designed for reliable operation in harsh environments, specified for an operating temperature range of -40°C to +85°C, making it suitable for industrial and automotive applications. The compact footprint facilitates easy integration into space-constrained designs. Internal filtering minimizes EMI, simplifying system-level compliance. This converter is ideally suited for powering sensitive analog circuitry, digital logic, and other low-power applications where isolation and stable voltage regulation are critical.
