3S8W_0509S2RP – GAPTEC

The 3S8W_0509S2RP is a compact, isolated DC-DC converter module designed for embedded power applications requiring a tightly regulated 9V output. It delivers a stable 333mA output current from a wide 2:1 input voltage range of 4.5V to 9V. The module incorporates robust galvanic isolation, enhancing system safety and mitigating ground loop issues. Its high efficiency of 81% minimizes heat dissipation, contributing to reliable operation across a broad temperature range of -40°C to +100°C. The converter utilizes a fixed-frequency switching topology to optimize performance and reduce output ripple. Internal protection features include short-circuit protection (SCP) and over-temperature protection (OTP), ensuring device longevity and system stability. The SMT-compatible package allows for automated assembly and minimizes board space requirements. This module is ideal for powering sensitive analog circuitry, digital interfaces, and other low-power components in industrial, telecom, and automotive applications.
