PMIC - LED Drivers are important components used to control a single or a group of LEDs in an electric circuit. The LX1990ILM-TR is an IC solution which helps manufacturers in efficiently achieving display dimming for television, monitor, and other LED back lit applications. It is a LED driver IC that provides LED current matching and excellent lighting performance.

The LX1990ILM-TR uses the constant current feature that offers maximum protection against abnormal load conditions and is provided with three control modes for the LED current. The current mode control enables the design of a low cost fixed frequency controller, while the voltage-mode control with pulse width modulation can be applied to boost controllers. Moreover, the IC is provided with an internal Over Temperature Protection (OTP) as an additional safety feature.

It is designed to offer up to 15 channels of LED current matching with minimal external components. Its LED driver IC is integrated with an Auxiliary Digital Amplifier Module (DAM), which helps the designers in providing a higher level of driving capability. Additionally, it is equipped with an embedded Power Good signal that enables the monitoring of the system based on the power supply voltages.

The LX1990ILM-TR is an adjustable leading edge dimming IC that supports a wide range of operating voltages from 2.6V to 5.5V. It features high switching frequency with fast PWM dimming ratio, thus offering excellent lighting performance. Furthermore, it provides a fast turn-on time of only 80us and low quiescent current draw of only 6 uA, making it highly energy efficient.

Additionally, LX1990ILM-TR comes with a built-in programmable current sink and source, which helps in providing smooth and uniform light intensities. It is designed to work with 3-axis magnetic sensors to detect orientation via tilt, yaw and roll. The high integration eliminates the need for expensive external components, which reduces the overall cost and size of the system.

This LED driver IC also offers a wide range of analog and digital dimming for different types of LCD panels and other LED back lit applications. The multiple PWM options allows the user to adjust the LED brightness to meet the desired requirements. It also features automatic standby modes for improved power savings and wiring detection that can assure stable lighting performance.

In conclusion, the LX1990ILM-TR is a versatile LED driver IC that offers high integration, low cost, low power consumption and excellent lighting performance. It is a multi-functional driver which can be used in various applications like LCD backlight, LED backlight, LED display and LED lamps.
