LED Driver ICs
Details
Power Integrations offers a broad range of highly integrated high power constant current LED driver ICs for use in LED applications where offline power supplies are requried at universal input line cord voltages from 85 to 265 VAC. Topologies include: boost, buck, buck-boost, and flyback.
Our LED Driver ICs offer:
- Phase-controlled TRIAC dimmability
- Single-stage power factor correction (PFC) and accurate constant current (CC) output
- High efficiency
- Compact size
- Low component count
- Long life
- Low maintenance
- Resistance to shock and vibration
- Generation of pure colored light
- Highly integrated
- Design-in made easy with PI Expert design tools
