QS7A_0505S3UP – GAPTEC

The QS7A_0505S3UP is a compact, isolated DC-DC converter module designed for applications requiring galvanic isolation and tightly regulated 5V output at 50mA. This module accepts a 4.5V to 5.5V input voltage, offering a ±10% tolerance window around the nominal 5V input. Utilizing a flyback topology, the converter achieves a typical efficiency of 73% across its operating range. The isolation barrier provides a minimum isolation voltage of ASSUME 1.5kV, as not specified. The device is encapsulated in a robust package suitable for harsh environments, enabling operation across a wide temperature range of -40°C to +85°C. Its low wattage (0.25W) makes it ideal for low-power applications such as sensor interfaces, isolated communication circuits, and powering digital logic. Internal filtering minimizes EMI, and comprehensive protection features, including short-circuit protection, ensure reliable operation. The small footprint facilitates easy integration into space-constrained designs.
