The AL1697-20CS7-13 is an LED driver from the PMIC (power management IC) product family. This driver is designed to provide an optimum combination of design simplicity, efficiency, and flexibility for LED applications.

The AL1697-20CS7-13 is an integrated LED driver IC which combines a PWM (pulse width modulated) LED controller, inductor-less buck regulator, power management and constant current control. It offers a complete single-chip solution for LED lighting applications. With its low-profile SOT23-6 package, high-efficiency power conversion, wide input voltage range and low quiescent current, it is ideal for applications including lighting control, decorative lighting, and security systems.

This integrated LED driver IC contains a high-efficiency buck regulator that operates with an input voltage range of 4.5 V to 40 V. It includes a PWM LED controller that offers adjustable LED brightness, color temperature control, flicker reduction, and built-in dimming. Additionally, the AL1697-20CS7-13 also provides voltage and over-current protection, as well as temperature monitoring. With its minimum operating temperature of -40°C, the AL1697-20CS7-13 is designed for a wide range of indoor and outdoor lighting applications.

The working principle of the AL1697-20CS7-13 is based on its pulse width modulated (PWM) LED controller. When the input voltage is applied to the power input terminal, the PWM will start controlling the LED brightness. The brightness of the LED is determined by the width of the output pulse. The output pulse varies in width depending on the input voltage and the PWM frequency, which can be adjusted as required. Additionally, the current through the LED is regulated by the PWM controller, and is limited to a safe level.

The AL1697-20CS7-13 also features a built-in energy-saving mode, which can be enabled by applying a low-voltage signal to the external enable pin. When in low-voltage mode, the LED current is reduced, and the LED will be dimmed. Additionally, the LED can be dimmed by controlling the PWM duty cycle. This allows you to control the LED brightness easily, while reducing power consumption.

The AL1697-20CS7-13 is a highly integrated LED driver IC with a wide range of features and functions. It is an ideal solution for lighting applications such as lighting control, decorative lighting, and security systems. With its high-efficiency power conversion, wide input voltage range, and low quiescent current, it is perfect for operating in harsh environmental conditions. It is capable of providing reliable, consistent, and safe lighting performance.
