QS4E_0303S1U – GAPTEC

The QS4E_0303S1U is a compact, isolated DC-DC converter module designed for point-of-load applications requiring a stable 3.3V output. This module delivers a tightly regulated 3.3V output at 75.7mA, providing 0.25W of power. The input voltage range is specified as 2.97V to 3.63V, representing a ±10% tolerance around a nominal 3.3V input. Galvanic isolation is incorporated to provide electrical separation between the input and output stages, enhancing system safety and noise immunity. The converter achieves a typical efficiency of 74% under nominal operating conditions. The QS4E_0303S1U is designed for robust performance across a wide operating temperature range of -40°C to +85°C, making it suitable for demanding industrial environments. The module utilises advanced switching techniques to minimize ripple and noise, ensuring a clean and stable power supply for sensitive electronic components.
