The QM48T45 Family is a QmaX™ DC-DC converter series in a through-hole quarter-brick, accepting 36 ~ 75 VDC and delivering 45 A at output voltages of 1.0, 1.2, 1.5, 1.8, 2.0, 2.5, and 3.3 VDC, with per-variant power up to 150 W. A single PCB layout covers all output voltage options, and every variant operates without a heat sink from -40°C ~ +85 °C. Output trim of -20% ~ +10% is standard across the family.
