LED drivers are an important component in the architecture of various electronic products, offering advanced solutions for efficient control, dimming and protection of LEDs. The L99LD20Q6TR is an integrated LED Driver ic specifically designed for low power applications. It works in conjunction with a buck regulator to provide a robust and accurate dimming control with PWM signals.

This device features wide dimming ratio coverage and over-temperature protection. The device is designed to balance the trade-off between brightness and power consumption. As such, the circuitry is simplified, resulting in higher efficiency, while still providing a wide selection of dimming options from full on/off to smooth dimming.

The L99LD20Q6TR has been designed for use in varyingly demanding applications, including automotive lighting, low-power lighting and systems with low EMIs. It works with the PMIC (Power Management IC), allowing for full monitoring and control of the LED current, as well as providing an accessible platform for extending the system to match more demanding LED applications.

The primary design goal of the L99LD20Q6TR is to achieve a homogeneous illumination in terms of color and brightness across the entire illumination area. This is possible thanks to the built-in, advanced compensation control circuitry. The feedback loop ensures that the LED current remains stable even in the presence of abrupt environmental changes, such as temperature swings and EMI interference.

The L99LD20Q6TR’s current configuration is based on proven linear technology and is fully adjustable, allowing it to be adapted to any LED current and load condition. This LED driver IC is also capable of providing a wide range of dimming ratios, including smooth dimming down to very low levels, in combination with its PWM input.

The device provides exceptional accuracy even at a glance levels of illumination. The combination of over-temperature protection and intelligent diming support ensures significantly longer life of the LED.

The L99LD20Q6TR is primarily intended for automotive applications, such as headlights, fog lights and daytime running lights, but it can also be used in commercial applications, such as lighting for homes and businesses, as well as for industrial applications, such LCD TV displays and signage.

The high level of integration in the L99LD20Q6TR makes it an extremely cost-effective solution for LED driver applications. It works in conjunction with the PMIC, allowing designers to fully monitor and control the LED current and ensuring maximum efficiency and reliability.

In summary, the L99LD20Q6TR is an ideal choice for a wide range of LED driver applications. It combines advanced compensation control circuitry with wide dimming ratios and over-temperature protection, making it an essential component in any low power LED system. Its high degree of integration ensures a cost-effective solution that is perfect for automotive, commercial and industrial applications.
