LYT1404D is a product of Lyttech, a PMIC - LED Driver. This comprehensive power supply solution is capable of controlling the light output of any LED application. It offers a high degree of precision and reliability, even when driving the most demanding LED applications.

LYT1404D is a self-contained PMIC LED driver solution consisting of a Constant Current Driver (CCD) and a Power Production Unit (PPU). The CCD is responsible for controlling the output current, while the PPU is responsible for providing the power necessary to drive the LED. Combined, they enable precision control over the brightness, color, and other aspects of the LED\'s operation.

The CCD implements a proprietary control circuitry that accurately drives the LED with a specified current. This current is typically set using a digital control register, which can be adjusted via an external pin, bypassing any other system components. The PPU, on the other hand, includes a buck regulator and a DC-DC converter. The combination of these two components provides versatile power management capabilities, including the ability to generate up to 5.5V from any supply voltage between 0.7V and 3.6V.

The CCD utilizes a combination of Pulse Width Modulation (PWM) and linear control to precisely control the LED current. The PPU uses a switch-mode boost converter to generate an output voltage that is higher than the input voltage. This combination enables the LYT1404D to deliver precise, consistent illumination across a wide range of forward voltage/current combinations.

The LYT1404D can drive any number of LEDs in series or parallel, allowing it to be used in a variety of applications. Some of the most common uses for this device include LED backlighting, LED display control, and LED illumination applications. The device is also suitable for automotive applications.

In addition to its reliable performance, the LYT1404D offers a host of features to maximize performance, reliability, and power efficiency. It is designed to operate with ultra-low power dissipation (<1μA), and to consume only 4mW of power when in use. The device also supports hot swapping, making it ideal for applications that require frequent re-configuration. Additionally, it comes with industry-leading safety features to protect against electrostatic discharge, over-voltage, and overcurrent conditions.

The LYT1404D is a versatile, high-performance PMIC - LED Driver. Its versatile control circuitry, efficient PPU technology, and robust safety features make it well-suited for driving the most demanding LED applications, including automotive applications. Moreover, the device\'s low power consumption, hot swapping capability, and industry-leading safety features make it an ideal choice for any LED application.
