The QT8E_0305S1U is a galvanically isolated DC-DC converter module designed for point-of-load applications requiring a regulated 5V output at 50mA. The module accepts a tightly controlled input voltage range of 2.97V to 3.63V (nominally 3.3V, ±10%). Isolation is provided via a transformer-based topology, ensuring robust separation between input and output circuits. The device delivers a maximum output power of 0.25W with a typical efficiency of 73%. Optimized for thermal performance, the QT8E_0305S1U operates reliably across an extended temperature range of -40°C to +85°C, making it suitable for demanding industrial environments. Internal circuitry incorporates protection features, though specific details are not provided. The module is designed for PCB mounting and offers a compact footprint. Detailed schematics and component specifications are available upon request.
