Product Summary

The LT1248CS#TR is a power fact controller. It uses a multiplier containing a square gain function from the voltage amplifier to reduce the AC gain at light output load and thus maintains low line current distortion and high system stability. The applications of the LT1248CS#TR include Universal Power Factor Corrected Power Supplies, Preregulators Up To 1500W.
