EAHC2835WD6 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 4-layer PCB with a large copper area for heat dissipation is recommended. The IC should be placed near a thermal pad or a heat sink to ensure efficient heat dissipation.
• How do I ensure the IC is properly powered on and off?
  The EN pin should be pulled high to turn on the IC, and pulled low to turn it off. A soft-start circuit can be used to prevent inrush current during power-on.
• What is the maximum allowable voltage on the VIN pin?
  The maximum allowable voltage on the VIN pin is 30V, but it's recommended to keep it below 25V for optimal performance and reliability.
• How do I adjust the output current of the LED driver?
  The output current can be adjusted by changing the value of the sense resistor (RSENSE) connected to the SENSE pin. A smaller sense resistor value increases the output current, while a larger value decreases it.
• What is the purpose of the COMP pin, and how do I use it?
  The COMP pin is used for loop compensation to ensure stability of the output voltage. A capacitor (typically 10nF to 100nF) should be connected between the COMP pin and GND to provide compensation.
