Подробное описание
The AL8862Q is a step-down DC/DC converter designed to drive LEDs with a constant current.
The AL8862Q operates with an input supply voltage from 5V to 55V and provides an externally adjustable output current up to 1A. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors. The AL8862Q switches at frequency up to 1MHz. This allows the use of smaller size external components, hence minimizing the PCB size.
The AL8862Q integrates the power switch and a high-side output current sensing circuit. Maximum output current of AL8862Q is set via an external resistor connected between the VIN and SET input pins. Dimming is achieved by applying either a DC voltage or a PWM signal at the CTRL input pin. The soft-start time can be adjusted using an external capacitor from the CTRL pin to ground. An input voltage of 0.3V or lower at CTRL pin will shut down the power switch.
The AL8862Q has been qualified to AEC-Q100 Grade 1 and is Automotive Grade supporting PPAPs.
