• MAX16805ATP+ Application Field and Working Principle

The MAX16805ATP+ is a highly efficient, step-down unit-antenna LED driver that belongs to the family of PMIC (Power Management Integrated Circuits) LED drivers.

The MAX16805ATP+ is a low-cost, four-channel LED driver that offers several advantages and features over other LED drivers. It operates over a wide input voltage range from 4.5V to 36V, making it suitable for both low and high voltage applications. The MAX16805ATP+ is an ideal solution for automotive, industrial, and portable electronics applications. The high-efficiency, low-noise operation, fast switching frequency, and small footprint of the device make it an attractive option for use in these applications.

The MAX16805ATP+ is a 4-channel, step-down LED driver that operates at a fixed frequency of 2MHz. The device uses Multi-Mode architecture to offer low-scroll mode, medium-scroll mode, and stand-by mode. The device also has over-current, over-voltage, and over-temperature protection features that help ensure device reliability.

The MAX16805ATP+ is designed with integrated gate-drivers to ensure robust and accurate gate control of the external MOSFETs. The gate drivers reduce the number of external components required in an application and enable easy control of the external MOSFETs. The integrated gate-drivers also offer fast radio frequency response to external changes that improves system efficiency.
