QS4E_0312S1U – GAPTEC

The QS4E_0312S1U is a compact, galvanically isolated DC-DC converter module designed for point-of-load applications requiring a regulated 12V output. It accepts a tightly regulated input voltage within the range of 2.97V to 3.63V (±10% tolerance). The module delivers a stable 12V output at 20.8mA, providing a power output of 0.25W. Isolation is a key feature, providing functional isolation between the input and output stages. The converter operates with a typical efficiency of 74% across its specified input voltage range. It is designed for robust performance in demanding environments, with an operating temperature range spanning from -40°C to +85°C. The device employs a fixed-frequency switching topology to minimize output ripple and noise. Internal protection features include short-circuit protection and over-temperature shutdown enhancing reliability and preventing damage under fault conditions.
