Working Principle

The NCL30081ASNT1G LED Driver operates using Pulse Width Modulation (PWM). PWM works by converting the DC input voltage into AC. This AC wave sets up a frequency, which is then used to control the brightness of the LEDs connected to the driver. The LEDs are dimmed or brightened according to the PWM signal applied to them.

When the input voltage and frequency are low, the LEDs are dimmed. When the input voltage and frequency are high, the LEDs are brightened. The PWM dimmer controls the on and off period of the LEDs, which in turn affects the LED brightness. The LED brightness is also affected by the LED current, which is controlled by the driver.

Application Field

The NCL30081ASNT1G LED Driver is suitable for a wide range of applications, including automotive, home lighting, industrial, medical, and more. In automotive applications, the NCL30081ASNT1G can be used in interior and exterior lighting, dashboard indicators, and more.
