The AL5801W6Q-7 is an AC-DC LED PWM driver that excels in providing power to LED modules from an alternating current (AC) voltage. It can convert an AC voltage between 85V and 265V to a DC voltage as high as 375V for up to 6 LEDs. This makes it ideal for applications in which AC voltages can vary, such as in street lamps, traffic lights, and other outdoor lighting. As a result, the AL5801W6Q-7 is a popular choice in the market of PMIC (Power Management IC) LED Drivers.

The AL5801W6Q-7 has several features that make it an excellent power source for LED modules. Its average minimum output current of 6A and peak current of 12A allow for the powering of multiple LEDs in parallel, making it suitable for applications requiring an even illumination. In addition, its integrated cooling system is designed to keep the circuit temperature in an optimal range for safe operation. This helps to protect the LED module from any thermal damage due to excessive heat.

Moreover, the AL5801W6Q-7 is equipped with several advanced protection features to ensure long-term, reliable performance. The over-temperature protection feature automatically shuts off the power supply in the event of overheating. The device also has over-voltage protection, which is particularly useful when powering LED modules with AC voltages. In addition, the AL5801W6Q-7 is also protected from short circuits and over-loads.

The working principle behind the AL5801W6Q-7 is fairly simple. It utilizes an internal full-bridge rectifier circuit to convert an AC voltage into pulsating DC voltage. This DC voltage is then amplified by a PWM (pulse-width modulation) circuit, which produces a stable output. The output is then regulated using a switching regulator, which ensures a consistent out voltage and adjustable output current. The device is also designed with a constant voltage and constant current control circuit to ensure a safe and reliable operation.

Due to its exceptional features and great reliability, the AL5801W6Q-7 has become a popular choice in PMIC (Power Management IC) LED drivers. With its integrated cooling system, advanced protection features, and reliable operation, the AL5801W6Q-7 is an excellent solution for applications in which AC voltages can vary, such as in street lamps, traffic lights, and other outdoor lighting. It provides a dependable power source for LED modules and is suitable for powering multiple LEDs in parallel.
