Part 9: Troubleshooting Common Issues
| Symptom | Likely Cause | Solution | | :--- | :--- | :--- | | LEDs flicker at idle | Input voltage drops below dropout (e.g., 11V to 8V during cranking) | Add a large capacitor (2200µF) before the IC or use a boost-buck converter. | | IC gets hot instantly | R_sense too low (overcurrent) or PCB lacks heatsinking | Recalculate R_sense; add thermal vias and a heatsink. | | No light, but voltage at VIN | Open circuit in LED string | Check LED connections. The Highway 09 will output VIN to OUT when open load. | | Dim output after 10 minutes | Thermal foldback active | Improve cooling. Reduce input voltage (use a 12V regulated supply instead of 14.4V). | | High-frequency whine | Ceramic capacitor piezoelectric effect | Use an electrolytic capacitor in parallel or switch to a different dielectric (X5R instead of X7R). | Architecture : 8-bit CPU designed for low power consumption
