With the ever-increasing demand for light output, engineers are in need of efficient and cost effective solutions to power the LEDs in their lighting products. The LNK410EG offers a variety of features and characteristics that make it suitable for powering high-power, high-efficiency lighting applications.
The LNK410EG is a PFC controller and mobile power interface combination integrated power device designed to drive high brightness LEDs with high efficiency and low electromagnetic interference (EMI). The device also provides integrated protection and fault detection for better product reliability.
Features
- Power fidelity control (PFC) dedicated design
- Analog current-mode control
- Low inductor current ripple for improved EMI performance
- High system efficiency up to 97.5%
- Temperature compensation
- Undervoltage protection
- Overtemperature protection
- Short-circuit protection
- Overvoltage protection
Application Field
The LNK410EG has been designed to be used in a variety of LED lighting applications, ranging from power sources for LEDs in general lighting, backlighting for LDC displays, Automotive Lighting, Emergency Lighting, and more.
The device supports a wide range of input voltages from 11V to 44V, and is able to drive up to seven strings of LEDs (one primary and six secondary) at currents up to 500mA per string. This makes the LNK410EG a great fit for designing solutions that require greater flexibility or offer more features in the same lighting application.
Working Principle
The LNK410EG utilizes power factor control principle, converting AC input power into regulated control with higher efficiency. The voltage feedback sensed by the voltage divider is compared to a reference voltage by the internal error amplifier, thus the inductor current is adjusted accordingly based on the output.
The inductor current ripple detection circuit uses a voltage sense resistor to detect the current ripple. The detected current ripple is then fed into the feedback loop of the internal error amplifier, thus according to the detected current ripple, the regulator can adjust the DCIN voltage and LED output current to optimize the efficiency.
The device further provides Over Temperature Protection (OTP) circuit and UVLO circuit to provide protection for internal components and LED strings from over current, over voltage and temperature rises, making sure the lighting products can work stably and securely.
Conclusion
The LNK410EG power IC is a great solution for high power LED lighting applications, offering high efficiency, low EMI, and overvoltage/overtemperature protection. Its power factor control principle, wide input voltage range and support up to seven LED strings makes it a great fit for LED lighting applications where flexibility or added features are needed.
