Product Description
- 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

Chipworker Certification
