QT8B_1203S3UP – GAPTEC

The QT8B_1203S3UP is a compact, isolated DC-DC converter module designed for point-of-load applications. It accepts a nominal 12V DC input (10.8V – 13.2V range, ±10% tolerance) and provides a regulated 3.3V DC output at 76mA, delivering a power output of 0.25W. The module utilizes a flyback topology to achieve electrical isolation between the input and output, enhancing system safety and noise immunity. With a typical efficiency of 78%, the converter minimizes power losses and heat generation. The operating temperature range spans from -40°C to +105°C, making it suitable for harsh industrial environments. The module’s robust design ensures reliable performance across a wide range of operating conditions, making it ideal for powering sensitive electronic components in demanding applications. Internal protection features include short-circuit protection and thermal shutdown.
