QS4A_0305S1.5UP – GAPTEC

The QS4A_0305S1.5UP is a compact, galvanically isolated DC-DC converter module designed for point-of-load applications requiring a stable 5V output at 50mA. This module operates with a tightly regulated input voltage range of 2.97V to 3.63V (±10% tolerance), providing a regulated output even with minor input voltage fluctuations. With a power rating of 0.25W, the QS4A_0305S1.5UP achieves a typical efficiency of 75%, minimizing power dissipation and enhancing thermal performance. The isolation barrier provides robust electrical isolation between the input and output, crucial for safety and noise immunity in sensitive applications. The module is designed for reliable operation across a wide temperature range of -40°C to +105°C, making it suitable for demanding industrial environments. Its compact form factor facilitates easy integration into space-constrained designs.
