Critical Conduction High Power Factor LED Controller
The AAL412 is an LED controller capable of driving one or more string of LEDs with high efficiency and power factor correction. A host of novel features such as self-oscillating and critical mode of operation, PFC capability, together with low power dissipation make the AAL412 a truly breakthrough product which will establish standards for future “green” lighting technology.
Features - Unique self oscillating with optimized PFC controller able to drive hundreds of White LED diodes, typically 120 to 1000 from an AC source, 10 to several hundreds from a DC source
- 12VDC to 265V AC sources and beyond
- Constant current LED operation for maximum LED brightness, maximum life and reliability
- Built-in PFC for low harmonic distortion and Power Factor Correction,
- High-efficiency > 95% to save power and reduce heat dissipation
- LED current control and overvoltage protection
- Usable in both boost- and flyback-based designs
Applications
- AC/DC LED Driver Applications
- DC/DC LED Driver Applications
- RGB backlighting
- Backlighting of LCD and PDP panels
- LED signs
- LED decoration
- Automotive
- Road signs, traffic lights
