LED Drivers are a kind of versatile electronic component used for driving light-emitting diode (LED) products. Among them, LXV250-052SW (hereafter referred to as LXV) is one of the latest types available in the market. This article will introduce the application field and working principle of LXV.

The LXV series is designed specifically for driving light LED applications, especially for a wide variety of LED lighting products. Compared to the traditional led driver technologies, LXV has significantly improved in terms of power efficiency, robustness, quality and system compatibility. Specifically, LXV has an ultra-low on resistance of 4.5 mΩ in full load condition, making it the optimal choice for stable output power supply.

The LXV series LED driver is designed with simple circuit topology and multiple safety protections. In particular, its open circuit protection function, over-voltage protection function, short circuit protection function and temperature protection function can ensure an ultra-low output temperature rise, safe and reliable working environment. Furthermore, LXV’s step-down power supply can work normally even when the input voltage is higher than the output voltage, thereby making it capable of driving current up to 1.4A.

The working principle of LXV is based on PWM control and a power conversion circuit. The PWM pulse is generated by a built-in high-precision oscillator. When the voltage of control port rises, the pulse width increases, which makes the output voltage increase proportionally. Concerning the power conversion circuit composed of MOSFETs, p-channel and n-channel ones, the two MOSFETs form a power switch pair. When the n-channel MOSFETs are turned on , the output voltage decreases, the p-channel MOSFETs are turned on and the output voltage increases.

Put it simply, LXV is specifically designed for driving LED products with high efficiency, safety and performance. Its safety circuit protection, temperature control and PWM control provide the necessary features for diverse LED applications. With such an ideal driving system, LXV is widely applied to LED tube, LED strings and LED modules, providing a great contribution to LED energy-saving lighting.
