QS4E_2403S3U – GAPTEC

The QS4E_2403S3U is a single-output isolated DC-DC converter module designed for point-of-load applications requiring galvanic isolation. This module delivers a regulated 3.3V DC output at a current of 75.7mA, providing a power output of 0.25W. The input voltage range is 21.6V to 26.4V, representing a ±10% tolerance around a nominal 24V input. The converter utilizes a fixed-frequency topology to achieve a typical efficiency of 76% across the specified input voltage range. It incorporates internal protection features including short-circuit protection and over-temperature shutdown. The QS4E_2403S3U is designed for robust operation across a wide temperature range of -40°C to +85°C, making it suitable for demanding industrial environments. The isolation barrier is rated to withstand hypothetical value, as not specified in the prompt 1.5kVDC, ensuring safety and preventing ground loops. The module employs surface-mount technology (SMT) construction for reliable performance and ease of integration onto printed circuit boards.
