LT1249
LT1249 - Brand New Analog Devices / Linear Technology PFC (Power Factor Correction)
- One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
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 Driver
APPLICATIONS
■ Universal Power Factor Corrected Power Supplies
■ Preregulators up to 1500W
