QS4E_0305S1U – GAPTEC

The QS4E_0305S1U is a compact, isolated DC-DC converter module designed for point-of-load applications requiring a tightly regulated 5V output at 50mA. The module accepts a nominal 3.3V input with a wide input voltage range of 2.97V to 3.63V (±10% tolerance), providing robust operation across various power supply conditions. Isolation is provided between the input and output, enhancing safety and reducing ground loop issues. With a typical efficiency of 74%, the converter minimizes power dissipation while delivering a stable 0.25W output. The QS4E_0305S1U is engineered for reliable performance in harsh environments, operating within a wide temperature range of -40°C to +85°C. The isolated design and wide temperature range make it suitable for industrial control systems, instrumentation, and other applications demanding robust and reliable power conversion.
