PMIC - LED Drivers

LED lighting is becoming increasingly popular due to its power efficiency, longer lifespan and relatively low heat production. LED drivers enable LED lighting systems to be used in various applications and can be found in many types of markets including commercial, industrial and residential. TPS92001DGK is one of the most popular and reliable LED driver solutions in the field.

Application Field of TPS92001DGK

The TPS92001DGK driver is designed for use with common LED types such as high-power LEDs, chip-on-board (COB) LEDs, and other compatible linear and power LEDs. It is a high-efficiency driver that operates at a wide input voltage range of 7V to 28V, making it suitable for many different power inputs. Thanks to its wide input range and high efficiency, the TPS92001DGK is suitable for a wide range of conditions, including automotive, industrial, commercial and residential applications.

The driver offers good protection against short-circuit, open circuit, over-voltage, under-voltage, and over-temperature conditions. It also maintains high efficiency while its operating temperature range can go up to 105°C, making it suitable for a wide range of temperature. It is equipped with protection features such as over-temperature protection, short circuit protection, and over-voltage protection.

Working Principle of TPS92001DGK

The TPS92001DGK driver controls current in two phases. In the first phase, control is done by pulse width modulation (PWM). This method is used to regulate the average current flowing through the LEDs, making sure that current levels are under control and that the LED array can be driven without risking any damage. PWM is also used to dim the LED output if the need arises. The second phase is done using analog current control (ACC), which fine-tunes the LED current based on the input voltage.

In order to obtain the highest possible efficiency, TPS92001DGK also implements a power-tracking algorithm. This algorithm constantly adjusts the input voltage and current to ensure that they are balanced and that the most efficient operation is obtained. This ensures high efficiency and helps extend the lifetime of the LED drivers.

Moreover, the driver also has built-in EMC protections which protect against electro-magnetic interference. This helps to keep the system running smoothly and prevents any type of interference from outside sources.

Conclusion

The TPS92001DGK is a reliable and high-efficiency LED driver suitable for a wide range of applications. It features a wide input voltage range, high efficiency, and protection features to ensure longevity of the driver and the LED system. In addition, it also has power-tracking and EMC protection features to ensure a high performance LED system.
