QT8A1_0309S1.5UP – GAPTEC

The QT8A1_0309S1.5UP is a compact, unregulated DC-DC converter module designed for isolated power applications. It accepts a 3.3V nominal input voltage with a ±10% tolerance window, accommodating input voltages from 2.97V to 3.63V. The module provides a single, isolated 9V output at 28mA, delivering a maximum power output of 0.25W. Employing a flyback topology, the device achieves a typical efficiency of 77% across its operating range. This module provides galvanic isolation between the input and output stages. The robust design ensures reliable operation across a wide temperature range, from -40°C to +105°C, making it suitable for harsh industrial environments. The module is designed for PCB mounting and offers a cost-effective solution for applications requiring isolated DC power.
