The QT8B_1215S3UP is a compact, isolated DC-DC converter module designed for point-of-load applications requiring a regulated 15V output. This single-output module delivers a stable 16.7mA, providing a maximum power output of 0.25W. It accepts a tightly regulated input voltage range of 10.8V to 13.2V (±10% tolerance around a nominal 12V input). Employing a fixed-frequency switching topology, the converter achieves a typical efficiency of 78% across its operational range. The robust design ensures reliable performance across a wide temperature range of -40°C to +105°C, making it suitable for harsh industrial environments. Isolation is provided between the input and output stages, enhancing system safety and reducing ground loop issues. This module is ideal for powering sensitive analog circuits, instrumentation, and isolated control systems.
