MAX8834YEWP+T, a member of Maxim Integrated must switch family of integrated power solutions, is a touchscreen power management IC. It was created specifically to offer smart power management solutions to touch-enabled portable electronics applications such as smart phones, media players, and tablets.

The MAX8834YEWP+T is a single step up converter with extensive protections and a typical efficiency of over 94%. It integrates a 2A DC-DC step-up controller and PMOS buck switch, required support components, and programmable undervoltage lockout (UVLO) as well as thermal protection functions on a single monolithic IC.

MAX8834YEWP+T contains a single buck switch and buck-boost controller capable of delivering up to 6A peak (3A continuous). It can deliver up to 3A of power for its integrated buck regulator and up to 8A of power for its two integrated boost regulators. It also features two control loops for precise voltage regulation.

The MAX8834YEWP+T is flexible enough to handle most applications requiring a regulated power supply. It offers several protection features including over-current protection, over-temperature protection and an adjustable soft-start function. Furthermore, the device comes in a compact 4mmx4mm QFN-24 package and has a wide input voltage range (1.7V-6.0V).

The MAX8834YEWP+T’s application field lies mainly in PMIC-LED drivers, as a single IC to provide constant power for devices with large power loads, especially for low power LED applications. This chip ensures a stable, efficient and adjustable AC-DC power management solution. This can be used to drive LED bulbs, LED strips and LED monitors.  With its built-in overcurrent protection, soft start, adjustable PWM frequency, current sense accuracy and its fast fault response, MAX8834YEWP+T makes LED driver designs reliable, safe and cost effective.

The MAX8834YEWP+T’s working principle is relatively simple. When it is powered up, the MAX8834YEWP+T will detect the output voltage and adjust the duty cycle of the step-up converter to maintain the set voltage in the safe range. In other words, the system will reduce the duty cycle to decrease the output voltage and increase the duty cycle to increase the output voltage. Its over-current protection will help power the LED lights safely by preventing it from reaching dangerously high levels. If a fault is detected by the MAX8834YEWP+T, it will protect itself from damage by immediately shut down the output and alert the user of the potential problem.

In conclusion, the MAX8834YEWP+T is an integrated power solution designed for PMIC-LED Drivers. It is ideal for low power LED applications, providing a regulated power supply with a wide input voltage range, over-current protection, adjustable soft-start and a fast fault response. It is a cost-effective solution that makes efficient, reliable, and safe LED driver designs possible.
