LED Drivers are vital components of power management integrated circuits (PMICs). The main function of PMICs is to regulate and protect the power supply of an electronic device, ensuring it is driven safely and efficiently.

The TCA62724FMG EL is a dual-channel LED driver with adjustable current, designed for driving and dimming high brightness LEDs. This advanced LED driver offers precise current setting, wide constant current range and high power efficiency.

The TCA62724FMG features 4 independent LED drivers, each capable of delivering up to 350mA of LED current, providing a total of 1400mA for devices such as backlighting for LCD displays in mobile phones, digital cameras and PCs. The device also features an adjustable boost voltage converter that offers an output voltage up to 18V and provides a regulated output current.

The TCA62724FMG is versatile; with adjustable LED current it can be used to drive different types of LEDs with varying current needs. The 4 independent LED drivers can be used to create different light effects, such as driver LED fading, pulsed LED dimming, and color mixing functions. The TCA62724FMG also includes an on/off dimmer input which allows the user to switch between low and high brightness modes.

The TCA62724FMG is designed to control the current flow to LEDs, using a constant current control technique. The device directly monitors the voltage across the current sense resistor to determine the correct current level to the LEDs. The current is then adjusted in small increments to maintain a consistent level, providing flicker free lighting effects. The device also features an over-temperature protection, which limits the current in order to protect both the device and the LEDs from overheating.

The TCA62724FMG is an excellent choice for LED driver applications and can be used to drive not only LCD displays, but also LED applications such as car lighting and lighting systems. This highly flexible device offers a wide variety of features, including adjustable LED current and dimmer functions, as well as high current output, thermal protection, and a low footprint.
