Frequently Asked Questions

How do I select the right BPSemi LED driver for my application?

Selecting the right LED driver requires considering input voltage range, output current/power, dimming requirements, power factor needs, and safety standards. BPSemi offers solutions for various power levels and topologies. For high-power commercial lighting, consider isolated drivers with active PFC. For consumer applications, non-isolated solutions offer cost advantages. LiTong FAEs can help analyze your specific requirements and recommend optimal solutions.

Provide your application specifications to LiTong for personalized LED driver recommendations.

What dimming options are available with BPSemi LED drivers?

BPSemi LED drivers support multiple dimming methods including 0-10V analog dimming, PWM dimming, triac/phase-cut dimming for retrofit applications, and digital dimming interfaces. Some advanced drivers feature integrated MCU control for smart lighting applications. The dimming range typically extends from 1% to 100% with good linearity. Select drivers based on your control system requirements and compatibility with existing infrastructure.

Choose dimming method based on your control system. Contact LiTong for dimming compatibility guidance.

What is power factor correction (PFC) and when is it required?

Power factor correction minimizes phase difference between voltage and current, reducing reactive power and improving energy efficiency. Active PFC is typically required for lighting products above 25W in many regions to meet regulatory standards like EN61000-3-2. BPSemi offers LED drivers with integrated active PFC achieving power factors above 0.9. For lower power applications or cost-sensitive designs, drivers without PFC may be acceptable depending on local regulations.

For commercial lighting above 25W, select drivers with active PFC. Contact LiTong for regulatory compliance guidance.

How do I calculate the appropriate LED driver power rating?

LED driver power rating should be calculated based on LED string voltage and current requirements. Multiply LED forward voltage by number of LEDs in series to get output voltage, then multiply by LED current to get output power. Add 15-20% margin for driver efficiency and temperature derating. BPSemi drivers are available in various power ratings from 3W to 100W+. Always verify thermal conditions and actual operating parameters during design validation.

Use BPSemi's design calculators or contact LiTong FAEs for power rating calculations and thermal analysis.

What protection features do BPSemi LED drivers include?

BPSemi LED drivers incorporate comprehensive protection features including over-voltage protection (OVP), over-current protection (OCP), short-circuit protection (SCP), over-temperature protection (OTP), and LED open/short protection. These features ensure reliable operation and protect both the driver and LED load under fault conditions. Advanced drivers may also include input under-voltage lockout (UVLO) and thermal foldback protection.

Review protection requirements for your application. Contact LiTong for guidance on protection feature selection.
