LYT2005E are AC-DC converters and offline switchers, specifically designed for LED lighting applications. These off-line LED lighting switches provide the most reliable and affordable solution for LED lighting applications. The LYT 2005E is equipped with an advanced technology for high efficiency and low-noise operation. It is Self-driving & Self-Sensing Fail-safe Soft-Start, Over Temperature Protection (OTP), Active PFC and Digitally Controlled OVP enabling ultimate safety requirements. It is available in a range of different models with an output of 2V to 76V.

The LYT2005E ACDC converter has a power range of 3W to 200W and has a wide input voltage range from 90V-300V AC, making it suitable for worldwide applications. It also has a built in protection for over current, over voltage, open circuit and heat sink fault protection. The LYT2005E also has a high power factor of 99%, and a low-harmonic distortion of less than 10%. The LYT2005E is also very easy to install with integrated power module and a 10-15V input voltage.

The working principle of LYT2005E ACDC converter is based on a full bridge LLC converter. It uses a high frequency PFM(Pulse-Frequency modulation) Control technology to enable high frequency and high output ripple, while it’s resonant frequency is modified to achieve high efficiency. Its resonance frequency is adjustable and it can be shifted to reduce the switching loss or increase the output ripple. The LLC resonant control enables the converter to achieve very high efficiency at light load conditions with low audible noise.

The LYT2005E also has a built-in active power factor correction (PFC) circuit which compensates non linearity of the power input, increases power factor and reduces the harmonic distortion. The built-in PFC is fully digitally controlled and provides a maximum power factor of greater than 0.99.

In addition, the LYT2005E is equipped with advanced protection features, such as over temperature protection (OTP) and digitally controlled output over voltage protection (OVP). The OTP function protects the converter from high temperature and extends its lifetime. The OVP function protects the converter from unexpected output over current conditions. All these features help to provide a stable and reliable source of LED lighting.

Overall, the LYT2005E ACDC converter and offline switcher is a highly efficient and reliable solution for LED lighting applications. With its wide range of applications, advanced protection features and adjustable resonance frequency, it is an ideal choice for lighting installations worldwide.
