PMIC (Power Management Integrated Circuits) are used in many different types of applications and are often employed in consumer electronics such as laptops, tablets and other portable devices. LED drivers are one type of PMIC that are used to power LEDs, which are small, efficient and low-cost light-emitting diodes (LEDs). The LNK458KG is a high-performance, high-efficiency, compact and low-power LED driver specifically designed for driving and dimming of single or multiple LEDs in automotive, commercial and consumer applications.
The LNK458KG utilizes a peak-current-mode control scheme. This control scheme senses the peak current sensed across the external sense resistor and uses this information to maintain a regulated peak current in the LED load. The sense resistor is typically chosen based on the peak current desired in the LED, and the device monitors it in order to maintain a constant current.
The LNK458KG is provided with an open drain enable input, PWM dimming and programmable double-pulse detection. When PWM dimming is enabled, the LNK458KG can be instructed to turn on and off LED at specific points in time to produce a desired dimming effect. The open drain enable input allows the LED driver to be turned on and off with the application of a low-voltage control signal.
The LNK458KG provides several protection features to ensure the safety and reliability of the device. Its hiccup-mode is used to perform over-temperature and short-circuit protection. The device is also equipped with an over-voltage protection circuit that limits the voltage across the LED to prevent damage.
The LNK458KG can be used in various LED applications, including automotive, industrial and security. It is especially useful when powering high-power LED applications such as displays, illuminations and signage. Its high-efficiency and low-power operation make it an ideal choice for energy-efficient designs.
In summary, the LNK458KG is a versatile and high-performance LED driver specifically designed for driving and dimming high-power LEDs in a variety of applications. It is capable of providing a regulated peak current to the LED load and features a variety of protection features to ensure its reliability. With its peak-current-mode control scheme and programmable features, the LNK458KG is an ideal choice for powering LEDs in automotive, commercial, and consumer applications.
