QT8E_0503S1U – GAPTEC

The QT8E_0503S1U is a compact, isolated DC-DC converter module engineered for point-of-load applications requiring a stable 3.3V output. It accepts a tightly regulated input voltage range of 4.5V to 5.5V (±10% tolerance). This module delivers a precisely regulated 76mA output current, yielding a maximum power output of 0.25W. Isolation is a key feature, providing galvanic separation between input and output stages for enhanced safety and noise immunity. The converter achieves a typical efficiency of 73%, balancing performance and power consumption. Designed for robust operation in harsh environments, the QT8E_0503S1U is specified for an extended operating temperature range of -40°C to +85°C, making it suitable for industrial and embedded systems. The compact form factor facilitates easy integration into space-constrained designs, and its isolation characteristics mitigate ground loop issues.
