LED lighting technology is extensively used in a variety of applications. LED lighting typically includes a plurality of LEDs that are driven by a LED driver circuit. Further, LED lighting applications are typically driven by smart and power-efficient lighting and light-fidelity (Li-Fi) communication. The LED drivers can be used to control an intensity of light output by one or more LEDs, by outputting signals to an LED circuit that have predetermined current and pulse characteristics. However, most of the commonly used LED drivers either consume an excessive amount of power while operating in the constant current (CC) mode, and therefore suffer from thermal issues that prevent the LED drivers from being used for high-brightness lighting applications, or cause electromagnetic interference and low frequency flicker issues while operating in a power-efficient switched inductor (SI) mode.
Accordingly, there is a requirement for an improved LED driver that has a wide dynamic range and high power efficiency direct current dimming and can be used in diverse applications.
