Application Information (Continued)
Example 4: 6 Blue LEDs in parallel (2), I(LED) A0-20 mA
• Maximum current limited by ballast resistors (6)
• 1.5x or 2x mode can be used depending on application. If higher I(LED) accuracy is required then 2x mode is recommended.
• Brightness adjustment by programming
• Overlapping switch mode in use
• See Electrical Characteristics for output voltage and current specifications in different conditions
