PMIC-LED Drivers: LED1642GWXTTR Application Field and Working Principle

The LED1642GWXTTR is a unique PMIC-LED driver developed by NXP Semiconductors. It is primarily used to provide an efficient and cost-effective solution for powered or low-power devices. The 16-bit drivers and multiple modules allow users to easily control up to three sets of LEDs data and brightness in tight spaces. The LED1642GWXTTR is designed to solve the most challenging lighting applications, such as flat and thinning backlighting, pixel displays, automotive lighting and vision lighting.LED1642GWXTTR utilizes a high capacity DC to DC boost converter to supply the LEDs with the best efficiency. The LED1642GWXTTR output power is managed through pulse width modulation, and the output voltage can be adjusted between 0.4V to 9V. Equipped with a five input voltage ranges from 1.5V to 27V that allows adaptability with different LED characteristics and Thermal Auto Protection (TAP) that provides thermal shutdown, the LED1642GWXTTR is an ideal choice for diverse applications. Additionally, the LED1642GWXTTR\'s flexibility makes it suitable for devices that require hard dimming and flashing sequences.The integrated charge pump and boost converter, along with the available capacitive mode driver, allows the LED1642GWXTTR to be used in equipment which requires wide dynamic range and wide dimming range. The LED1642GWXTTR is built with reliable features, such as low power dissipation, fast reaction time and an integrated PWM dimming function. Because the LED1642GWXTTR is made with an auxilary power management path, it is capable of automatically sensing and adjusting the LED light output even in low current applications.The LED1642GWXTTR is composed of two main components- the power switch and the MOSFETs. The power switch, which controls the switching of the boost converter, and the MOSFETs, which control the dimming of the LED light output. Through the coordinated efforts of both components, the LED1642GWXTTR is capable of providing a very efficient and reliable operation.The LED1642GWXTTR also has the unique capability to drive up to three sets of LEDs in parallel. The LEDs are divided into two sections- red and blue, for easy identification and control. Each section can be independently controlled, allowing for up to 64 segments. As an added advantage, each set can be individually adjusted to match the required lighting effects and produce a variety of visual effects.The LED1642GWXTTR is based on NXP\'s standard 32-bit timer and module architecture. This makes it extremely powerful, flexible and can support up to 3 x 320KHz PWM outputs at a resolution of 524 steps. It also supports a variety of useful features such as single point dithering, Open Loop Voltage Mode Control, Two Buck converter control, Average Current Mode Control, Power Loss Compliance and is compatible with both SPI and I2C interfaces.Overall, the LED1642GWXTTR is a great option for users who need efficient lighting solutions that are both cost effective and high performance. With its wide-ranger dynamic range, built-in thermal protection and easily adjustable dimming, the LED1642GWXTTR can be used in a variety of applications and will always provide a reliable and efficient operation.
