This article is about NCL30095ADR2G, and the application field and working principle associated with it. In particular, NCL30095ADR2G is categorized as PMIC - LED Drivers.

NCL30095ADR2G is an advanced power management integrated circuit (PMIC) made by Texas Instruments. It is a high-side N-channel MOSFET driver and a pulse width modulation (PWM) dimming controller with advanced power management features and diagnostic capabilities.

The main application field of NCL30095ADR2G includes LED lighting systems, especially backlight dimming in LCD monitors and laptop computers, as well as automotive audio systems and lamp ballasts. These applications require precise control of currents and voltages, as well as improved system efficiency.

The NCL30095ADR2G consists of an integrated high-side N-channel MOSFET driver that provides a constant-on-time (COT) control. The PWM dimming controller has an adjustable hysteresis range that allows for accurate dimming control. The NCL30095ADR2G also features a low-current current source output (CPO) to ensure constant light output. Additionally, the IC is designed with the latest low voltage and high frequency power management design techniques.

The working principle of the NCL30095ADR2G IC can be best understood by looking at how it functions in LED lighting. In LED lighting, the IC uses a current feedback loop to control the LED current level. When the LED current level begins to drop, the IC increases the pulse width of the LED current to maintain a constant output.The IC then monitors the voltage level across the LED to ensure it remains within thresholds to prevent unwanted aging or burning.

The NCL30095ADR2G also offers over-temperature and over-voltage protection. In the event that the voltage level rises above a certain threshold, the IC will reduce the current to the LED. In the event that the temperature rises above a certain threshold, the IC will also reduce the current to the LED to prevent it from burning out.

The NCL30095ADR2G is also designed to be compatible with a wide range of LED configurations. This eliminates the need for external power sensing components, which can reduce cost and complexity in system design.

Overall, NCL30095ADR2G is an advanced PMIC - LED Drivers that offers precise control of currents and voltages as well as improved system efficiency. It is designed to work with a wide range of LED configurations and deliver advanced power management capabilities. It also offers over-voltage and over-temperature protection.
