LT1249 - Brand New Analog Devices / Linear Technology PFC (Power Factor Correction)
-
DESCRIPTION
The 8-pin LT® 1249 provides active power factor correction for universal offline power systems with very few
external parts. By using fixed high frequency PWM current averaging without the need for slope ompensation, the LT1249 achieves far lower line current distortion, with a smaller magnetic element than systems that use either peak current detection or zero current switching approach, in both continuous and discontinuous modes of operation.FEATURES
■ Standard 8-Pin Packages
■ 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 DriverAPPLICATIONS
■ Universal Power Factor Corrected Power Supplies
■ Preregulators up to 1500W -
