LT LT1248CN#PBF

平均电流300kHz

Overview

The LT1248CN provides active power factor correction for universal off-line power systems. By using fixed high frequency PWM current averaging, without the need for slope compensation, the LT1248CN achieves far lower line current distortion with a smaller magnetic element than systems that use either peak-current detection or zero current switching approaches in both continuous and discontinuous modes of operation.

The LT1248CN provides many protection features including peak current limiting and overvoltage protection, and can be operated at frequencies as high as 300kHz.
