The 3S7BE_1215S3U is a highly efficient, isolated DC-DC converter module designed for point-of-load power applications. This module provides a regulated 15V DC output at 200mA, delivering a total output power of 3W. The input voltage range is specified as 11.4V to 12.6V, representing a ±10% tolerance around a nominal 12V input. Utilizing advanced switching topologies, the converter achieves a typical efficiency of 90% across the specified input voltage range and load conditions. The isolation barrier provides robust electrical isolation between the input and output, enhancing system safety and reducing ground loop issues. The module is designed for reliable operation across a wide temperature range of -40°C to +85°C, making it suitable for demanding industrial and embedded applications. Internal protection features include over-current protection (OCP) and short-circuit protection (SCP).
