Frequently Asked Questions

What is the difference between linear and switching LED drivers?

Linear drivers are simple and low-cost but less efficient (especially at high voltage differential). Switching drivers (buck, boost, buck-boost) are more efficient but more complex. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Use linear for low current or small voltage differential. Use switching for high current or large voltage differential.

What is constant current regulation?

Constant current regulation maintains a fixed current through the LED regardless of input voltage or LED forward voltage variations. This ensures consistent brightness and LED lifetime. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Always use constant current drivers for reliable LED operation.

What dimming methods are available?

Common dimming methods include PWM dimming (fast on/off switching), analog dimming (current adjustment), and digital dimming (interface control). PWM is most common for its linear response. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Choose PWM for best dimming linearity.

How do I calculate LED driver power dissipation?

For linear drivers: Pd = (VIN - VLED) × ILED. For switching drivers, calculate based on efficiency. Ensure thermal design can handle the dissipation. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Contact FAE for thermal calculations.

What protection features are important?

Important protections include over-voltage protection (for open LED), over-current protection, and thermal protection. These prevent damage during fault conditions. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Ensure driver has OVP for open LED protection.
