The AAL403 is an LED controller capable of driving a string of LEDs with high efficiency. The novel feature of a feedback function intended to control an upstream power supply, together with low power dissipation, makes the AAL403 a breakthrough product which will establish standards for future “green” lighting technology.
Features
- Has an internal FET for simple, compact, low-cost implementation
- External resistor for current-set function provides ultimate flexibility
- Constant current LED operation for maximum LED brightness, maximum life and reliability
- Feedback function to optimize efficiency
- PWM brightness control
- Built-in oscillator for blinking
- Thermally enhanced package allows for higher power in a small footprint
- Over-Temperature Shutdown
- Over Current Protection (Typically 180mA for 8-Pin SOIC, 400mA for 5-Lead TO-220 Packaged Versions)
Applications
- AC/DC LED Driver Applications
- DC/DC LED Driver Applications
- RGB backlighting
- Backlighting of LCD and PDP panels
- LED signs
- LED decoration
- Replacements for incandescent and fluorescent bulbs and fixtures
- Road signs, traffic lights
