AL5815W5-7 is a PMIC - LED driver designed for both high current or low current applications. It provides high efficiency and a wide voltage input range. It can be used for circuit as simple as driving a single point of light, or as complex as a series of LEDs with cascading effects. The AL5815W5-7 can be used to drive up to 5A or 7A output current.

Working Principle

The AL5815W5-7 uses a Step-Down Conversion Method to achieve its high efficiency. This technique involves the use of a Pulse Width Modulation (PWM) signal to vary the amount of time the input power is applied to the output voltage. Using this method, the output voltage is kept at a constant level and is regulated by the amount of time each cycle is active. This also results in high efficiency and very low power loss.

The driver also employs a dual loop feedback system to make sure the output voltage remains constant. The first loop is a voltage loop that measures the output voltage and adjusts the output power appropriately. The second loop is a current loop which measures the output current and adjusts the duty-cycle of the PWM signal. This allows for better control over the output power.

Applications

The AL5815W5-7 is designed for a variety of applications including LED lighting, automotive, industrial, and medical applications.

Its wide voltage input range makes it suitable for use in high-voltage applications, such as automotive and industrial applications. Additionally, its high efficiency and low power loss make it suitable for medical applications where precise power control is required.
