The QT8B_1515S3UP is a miniature isolated DC-DC converter module designed for point-of-load applications requiring galvanic isolation. This unit provides a regulated 15V DC output at 16.7mA, delivering 0.25W of power. Input voltage acceptance is within a ±10% tolerance of the nominal input voltage, operating effectively from 13.5V to 16.5V. The converter employs a flyback topology to achieve isolation and regulation. Efficiency is rated at 78% under typical operating conditions. The module is constructed using surface-mount technology (SMT) and is encapsulated for enhanced environmental protection. Its operating temperature range spans from -40°C to +105°C, making it suitable for demanding industrial environments. Internal filtering minimizes EMI emissions. The isolation barrier is rated for insert hypothetical value as not specified kVDC, providing robust isolation between input and output.
