A wide variety of LEDs have become commonplace in many different types of applications due to the rapid advancement of the technology during the past few decades. From traditional, general purpose LEDs to more specialized types such as high-power, constant current, and programmable, the variety of available LEDs is vast and continues to expand. The success of LEDs is largely made possible by the components used to power and control them, commonly referred to as LED drivers. One such driver is the BCR402RE6433HTMA1, which is classified as a PMIC - LED Driver since it provides a two-stage solution to driving LEDs in a variety of applications.

The BCR402RE6433HTMA1 has some key features that make it advantageous in various applications. It is designed to provide smooth LED transition throughout a wide selection of LED currents. For example, the LED current range when the device is on is 0.8mA to 6mA and when the device is off, it is less than 0.1mA. Thanks to its two stage linear architecture, there is minimal variation in LED brightness, maximizing the dynamic range and providing a smooth, consistent brightness transition. Additionally, the device supports analogue dimming, allowing for both MDPM (modulation of dimming pulses) and PWM (pulse-width modulation) dimming controls.

When regarding operation, the BCR402RE6433HTMA1 works similarly to other LED Drivers. The LED driver outputs the LED value upon receiving the LED control settings from the controller. The LED control input (CONTROL) controls the LED current through biasing the output of the LED driver to the desired voltage level. Depending on the LED current settings, the LED driver adjusts the biasing voltage at the output node to adjust the LED current. As a final precautionary step, the LED driver compares the LED current values with the output voltage. If the LED current settings are lower than the actual output voltage, the LED driver will turn off the LED current. Overall, the device has been specially designed to address the high common mode noise and to reduce the radiated EMI within its application field.

The BCR402RE6433HTMA1 is primarily designed for applications featuring high-power, constant current LEDs. It is suited for various general illumination applications such as lamps, street lighting, and down lighting for general lighting applications. Moreover, the device also works great for vehicle, machine, and automation-type lights. The device includes a set of internal protection features, including thermal protection, over-voltage protection, over-temperature protection, and over-current protection to protect itself and LED components from damage due to undesired conditions. It additionally has two frequency selectable dimmable dimming controls to enable adjustable LED dimming.

The BCR402RE6433HTMA1 LED Driver is designed to be reliable and cost-effective, making it a great choice for driving LEDs in a variety of applications. With its wide range of features, the device is a great option to consider for the power and control of LEDs in lighting application. Thanks to its reliable performance and user-friendly control input, the device is ideal for applications where accuracy, reliability, and flexibility are important.
