Overview

LT1248 Power Factor Controller U GND 1 – + FEATURES s s s s s s s s s DESCRIPTIO High Power Factor Over Wide Load Range with Line Current Averaging International Operation Without Switches Instantaneous Overvoltage Protection Minimal Line Current Dead Zone Typical 250µA Start-Up Supply Current Rejects Line Switching Noise Synchronization Capability Low Quiescent Current: 9mA Fast 1.
5A Peak Current Gate Driver The LT®1248 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 LT1248 achieves far lower line current distortion with a smaller magnetic element than systems ...
