This paper provides an introduction to the IS31FL3190-UTLS2-TR, which is an LED driver typically marketed as an LED driver but classified as an active PMIC due to its characteristics. This part can be used in various applications, including but not limited to displays, graphic panels, and industrial and commercial water displays. The main features of this part include the ability to drive LEDs individually, the ability to PWM control up to 16 channels, and the ability to perform matrix mapping for complex applications.

The IS31FL3190-UTLS2-TR uses a constant current mode to drive LEDs, which has the advantage of providing a highly consistent light output from the LEDs. This is especially important for applications that require a consistent light output, such as signage, displays, and backlighting. The IS31FL3190-UTLS2-TR can drive each LED individually, which allows for great flexibility in the design and programmability of the application. This can be used to create complex lighting effects, such as fading, blinking, and pulsing. The part can also be used to synchronize multiple channels of LEDs, allowing for a consistent light output across all channels.

The IS31FL3190-UTLS2-TR can also be used to PWM control up to 16 channels. This allows for dimming or flashing effects to be achieved with a single part, as well as programmability to achieve new effects. The part also has features, such as over-temperature protection, short circuit protection, over-current protection, and LED open circuit protection, all of which help to ensure that the part operates reliably and safely. The IS31FL3190-UTLS2-TR can operate from a supply voltage of between 2.7V and 5.5V.

Another unique feature offered by the IS31FL3190-UTLS2-TR is its capability to perform matrix mapping for complex applications. Matrix mapping allows for a single device to be used to drive a large matrix of LEDs, such as in displays or backlighting. The part can be programmed to map the LEDs in any desired pattern, allowing for complex lighting effects and creative designs to be created. This feature makes the IS31FL3190-UTLS2-TR a perfect choice for applications that require performance and flexibility.

In summary, the IS31FL3190-UTLS2-TR is an LED driver that is classified as an active PMIC due to its features and features. It is designed to drive LEDs individually with constant current, offer PWM control up to 16 channels, and can be used for matrix mapping for complex applications. With its versatile features and robust setup, it makes a great choice for LED applications that require performance and flexibility.
