LNK414EG Working Principle

The LNK414EG is a series of integrated, off-line, quasi resonant topology (QRT) SMPS controllers. Its main features include a quiescent current of 38 mA, a power factor correction of up to 99%, and an efficiency of up to 99.5%. The LNK414EG also provides a wide range of system solutions, such as active power factor correction, continuous drain current output, and high efficiency LED drivers.The basic protocol of the LNK414EG is to rapidly switch current on and off through a power FET in order to generate a low-noise, quasi-sinusoidal waveform. This waveform helps deliver power to the load without compromising in efficiency. The controller is also able to sense the current, voltage, and temperature of the output to regulate it for optimized power transfer.Additionally, the LNK414EG can be used with a wide range of power conversion solutions, from soft switching converters to fixed frequency and flyback transformers. It can also handle a wide range of power levels, from 5W to 1000W.

Conclusion

LNK414EG is a series of integrated off-line quasi resonant topology Switch Mode Power Supply (SMPS) controllers manufactured by Power Integrations Inc. It is designed to deliver a high efficiency, cost-effective and reliable solution for power conversion. The primary application fields of LNK414EG are LED drivers, solar power systems, HVAC systems and electric vehicle charging systems. Its working principle is based on rapidly switching current on and off using a power FET. It is suitable for power conversion solutions ranging from 5 W to 1000 W and over.
