LED drivers are used to control the operating current of LEDs. As the operating current of LEDs increases, the LED brightness increases and the system power consumption is reduced. LXV100-081S is an LED driver that uses a constant current circuit to control LED operating current and can adjust the operating current according to the ambient luminosity. It is widely used in LED lighting systems.

The LXV100-081S LED driver is mainly composed of an inductor, a boosted constant current circuit, a compensation circuit, a reference voltage circuit, a brightness control circuit and an isolation circuit, among which the boost constant current circuit is the core circuit. It uses a high gain voltage amplifier as a switching device, and a voltage comparator to detect the output voltage, the output voltage is used to control the switching time, so as to complete the high voltage output of the power supply.

The LXV100-081S LED driver is based on a PFC full-bridge buck-boost circuit. When the output voltage is unstable, the integrated MOSFET works with constant frequency protection, while the PFC full-bridge buck-boost circuit has the advantages of soft switching and the ability to maintain constant current. The output current is set with an external voltage reference and a feedback signal with an error amplifier, taking into account the parameters of the component, the accuracy of the output current is up to ±3%.

The LXV100-081S LED driver is also equipped with a feedback correction circuit. When the environment illumination changes, the output current can be adjusted to maintain constant brightness, and when the temperature changes, through the feedback correction circuit to maintain constant current accuracy. When the current output reaches the set current, the conversion remains constant until the input voltage reaches its maximum, so that the current remains stable.

The LXV100-081S LED driver is widely used in LED lighting systems because of its stable operation, high accuracy, wide operating temperature range and high efficiency. It has been applied in many scenarios such as outdoor LED street lights, hotel lighting, photographic lighting, and industrial lighting. Moreover, LXV100-081S LED driver also has different dimming methods, such as 0-10V, 10V PWM, time dimming and so on.

In summary, LXV100-081S LED driver is a constant current LED driver with high precision, wide operating temperature range and high efficiency. It is widely used in LED lighting systems and has different dimming functions for different scenarios. The LXV100-081S LED driver is a reliable and efficient solution for LED lighting applications.
