Characteristic Curves
Output vs. Temperature
180W convection cooled and 275W continuous with 200 LFM airflow. Derate output power to 50% at 70°C.
Efficiency vs. Loading
The high efficiency is achieved by using LLC technology, PFC topology minimizing switching losses. Synchronous SCHOTTKY or ultra-fast diode is
used as rectifier in MINT1275 family because of high output voltage level.
