The MAX8790AETP+ is a power management integrated circuit (PMIC) LED driver that delivers high output current accuracy and fast LED response times. The design is optimized for multi-function, multi-channel LED control such as gaming and backlighting applications, and it provides dimensioning control of current and brightness in the LED driver.

The MAX8790AETP+ can be used to drive both low- and high-current LEDs with reliable and stable results. It supports various kinds of discrete LEDs, and multiple LEDs can be connected in series up to a total of 16 channels. Each channel consists of a buck converter, common output, and PWM dimming. It also has external sensing, current steering, analog dimming, and multiple ON/OFF control functions.

A primary benefit of this device is its high output current accuracy. It integrates features to enable precise current control and step-down converters to ensure accuracy while driving LEDs. This provides higher reliability and longer lifetime to the LED system you are controlling. Its fast LED response time makes sure that LED brightness can be accurately adjusted, and complex lighting schemes can be adjusted quickly and reliably. Additionally, there are a number of fault protection features to ensure higher system safety and reduce system faults.

The MAX8790AETP+ can be used in a variety of lighting applications such as gaming, automotive, commercial, and industrial. It is capable of driving high-current LEDs and supporting up to 16 channels of LED control. Its fast response times and precise current control enable complex lighting systems to be implemented with great accuracy and reliability. The MAX8790AETP+ provides advanced features to enhance lighting system safety, while it is also cost-effective and efficient to boost system performance.

The MAX8790AETP+ has two primary stages in its working principle. The first stage is a high-speed modulation loop which contains a buck converter. This loop is designed to provide the precise current control and step-down to drive the LEDs with accuracy. It also adjusts the dimming of the LEDs based on the PWM signal input. The second stage is the current-sense loop which senses the current in the LED string and adjusts the drive current accordingly.

Together, these two stages work in tandem to ensure a precise and stable current in the LED driver, thus providing reliable results in the LED system you are controlling. It is also capable of providing various kinds of protection such as over-voltage, over-temperature, and short circuit protection. Additionally, it provides efficient power management while still delivering fast response times of brightness adjustments.

In conclusion, the MAX8790AETP+ PMIC LED driver provides unparalleled current accuracy and fast response times for multi-channel LED control applications. It supports a variety of LEDs including high-current LEDs and multiple LEDs connected in series. Its dual-loop design gives it precise current control and fast LED response times while providing protections like overvoltage, over-temperature, and short circuit protections. On top of that, its embedded features are cost-effective to boost system performance. The MAX8790AETP+ is an excellent choice for various kinds of lighting systems.
