Overview
The AL58263T24E-13 is a 16-channel, 16-bit PWM dimming constant-current LED driver manufactured by Diodes Incorporated. It features Adaptive Pulse Density Modulation (APDM) technology and offers ±0.1% current matching accuracy across all channels. The device operates within a supply voltage range of 3 V to 5.5 V and supports high-frequency PWM dimming for precise brightness control. Packaged in a TSSOP-24EP format with a tape and reel quantity of 2,500 units, it is designed for high-density LED lighting applications requiring uniform current distribution.
Feature Summary
- Integrates 16 independent constant-current output channels for uniform LED illumination
- Utilizes Adaptive Pulse Density Modulation to minimize flicker and improve efficiency
- Provides 16-bit PWM dimming resolution for precise brightness adjustment
- Ensures high channel-to-channel current matching accuracy
Applications
- High-density LED backlighting modules
- Professional LED lighting fixtures
- Automotive interior lighting systems
