LEDs are becoming more popular in many industries such as automotive, communications, and consumer electronics. They are largely used for lighting, especially for interior, as well as for visual signaling applications.

In order to properly drive these LEDs, a reliable power management integrated circuit (PMIC) device, such as the MAX20090ATP/VY+T, is necessary. This device offers protection, efficiency, and optimal LED performance by utilizing a combination of integrated circuits and linear regulators.

The MAX20090ATP/VY+T is an LED driver PMIC that provides LED lighting solutions for various LED applications, such as automotive, television, and small lighting fixtures. It provides both high efficiency and high performance, while at the same time being cost effective. This PMIC is capable of driving up to 16 LEDs at a maximum current of 2A and a voltage of 28V. It also features open LED, reverse battery, overvoltage, and overcurrent protections.

The MAX20090ATP/VY+T supports various topologies, either in linear or nonlinear mode. In a linear topology, the input power is fed through an internal oscillator, which sets the operating frequency. This is then used to drive an external transistor, and subsequently, the LEDs. In nonlinear topology, the PMIC is used to maintain a constant current, thus preventing any flickering from occurring in the light output.

The MAX20090ATP/VY+T also includes a burst mode operation, which reduces the power consumption by switching off the IC when the LEDs are not in use. This helps reduce the heat generation and allows for higher efficiency in low-power applications.

Another feature of this PMIC is its low-noise operation. This is achieved by utilizing noise filtering and current limiting. This makes the driver suitable for applications such as automotive lighting, in which the noise must be kept to a minimum.

Overall, the MAX20090ATP/VY+T is an ideal PMIC for driving LEDs in a variety of applications. It provides high efficiency, reliable protection, and noise reduction, all while being cost effective.
