The QT8E_1512S1U is a compact, isolated DC-DC converter module designed for applications requiring a stable 12V output from a nominal 15V (±10%) input source. Utilizing a flyback topology, this module delivers a tightly regulated 12V output at 21mA, providing 0.25W of power. Galvanic isolation is implemented to ensure robust protection and noise mitigation between input and output stages. The module operates efficiently at 73% across the specified input voltage range (13.5V – 16.5V). Designed for harsh environments, the QT8E_1512S1U boasts a wide operating temperature range of -40°C to +85°C, making it suitable for industrial and embedded applications. Internal over-temperature protection is included for enhanced reliability. The module is designed for through-hole PCB mounting and offers a reliable power solution in a small form factor.
