QS4E_0309S1U – GAPTEC

The QS4E_0309S1U is a compact, isolated DC-DC converter module designed for point-of-load applications requiring a stable 9V output. It accepts a tightly regulated input voltage range of 2.97V to 3.63V, providing ±10% tolerance around a nominal 3.3V input. This module delivers a fixed 9V output at 27.7mA, yielding a maximum power output of 0.25W. Isolation is incorporated to provide galvanic separation between the input and output stages, enhancing system safety and reducing ground loop noise. The converter achieves a typical efficiency of 74% under nominal operating conditions. Its robust design allows for operation across a wide temperature range from -40°C to +85°C, making it suitable for harsh industrial environments. Internal circuitry provides protection against short circuits and over-temperature conditions. The module is designed for easy integration into existing power systems.
