The NDQ Series of quarter‑brick DC‑DC converters is a new generation of non‑isolated 48 V to 12 V power modules with digital control. They deliver up to 1600 W DC‑DC conversion at 12.25 V output, offering ultra‑high peak efficiency of 98% and a flat efficiency curve DC‑DC converter profile. These high‑power density converters operate across a wide temperature range of ‑40 to +85°C with forced‑air cooling, making them a prime choice for data center 48 V to 12 V power supply and high‑power computing/storage applications. The series includes NDQ900, NDQ1300, and NDQ1600 models—covering 1300 W DC‑DC converters and 1600 W 12 V quarter bricks—all sharing the same footprint, mechanical attributes, and electrical functions.
