Epistar Corporation has developed the BD6067GU-E2, which is one of its main power management integrated circuit (PMIC) - LED drivers. The core of this driver is a high-efficiency DC/DC step-up or boost converter. The high reliability and long lifetime of this driver makes it perfect for use in many applications like the driving of high power LED string lights, spot lights and direct drive LED luminaires.

The BD6067GU-E2 offers high efficiency, flexibility, and performance, as well as being extremely cost-effective. It has a wide operating range of up to 36 volts, and can provide a maximum output current of 40A for single string LEDs or 10A for series of strings. With its high efficiency of up to 99%, this driver does a great job of keeping your LED strings burn at the same brightness for a long time.

The BD6067GU-E2 utilizes an advanced switching control architecture which ensures high power conversion efficiency and ensures the minimal of power wastage. This driver also incorporates either a PWM dimming method or an analog dimming input, along with a voltage-programmable constant current output. Furthermore, it can provide a constant voltage output as well, which makes it suitable for use as an LED power supply to drive LED systems.

The working principle of the BD6067GU-E2 is relatively straightforward when compared to other devices. This driver uses a combination of a Pulse-Width Modulation (PWM) control and an off-time switching control to achieve its high conversion efficiency. By combining the two types of control, it is able to achieve a smooth dimming characteristic over a wide range of input voltage, while consuming only minimal power.

The driver also features a dual, low-cost, low-noise output protector, with an adjustable output current limit. This ensures that the output current is always kept at a safe level. Additionally, the built-in LEDs and auto recovery circuits keeps the LED strings running safely without any unnecessary or lost energy.

The BD6067GU-E2 is also equipped with a variety of safety protections, such as soft start/stop, over-temperature protection, open-load protection, and short-circuit protection. These protections are crucial for ensuring the safety of everyone, and the protection from short circuit is especially important for the LED drivers since it can help to prevent damage the LEDs.

In conclusion, the BD6067GU-E2 is an excellent PMIC – LED driver that offers high efficiency, flexibility, performance and reliability. Its advanced control architecture and safety protections make it suitable for a wide range of applications, from driving high-power LED string lights to direct-drive LED luminaires. Furthermore, its low-cost, low-noise output protector helps to keep the output current at a safe level, and its dual output protector keeps the LED strings running safely without any unnecessary power loss.
