The NCL30060B2DR2G is a type of Power Management Integrated Circuit (PMIC). Specifically, it is a constant current-driven high efficiency step-down DC-DC converter, also known as a LED Driver. Being a constant current driver, the NCL30060B2DR2G is primarily used in conjunction with LEDs when an input voltage is reduced to an output voltage less than or equal to the LED’s forward voltage. With this configuration, the NCL30060B2DR2G is able to power up to six separate LEDs.

The converter contains a PWM control circuit, two MOSFETs, a drive circuit, and a PWM comparator. The pulsewidth of the output driving signal is determined by the specific parameters set by the user and is adjustable through an external potentiometer. The PWM comparator compares the combined signals from the frequency generator and the external potentiometer and generates the output pulse width to meet the specific requirements.

The user can also adjust the current output of the NCL30060B2DR2G by pulling the pre-charge control input pin CT to low. This re-adjusts the output current to match the runtime requirements.The NCL30060B2DR2G also incorporates a precision 0.1V reference, an error amplifier and current sense circuitry that provides precision current regulation. In addition, the device features current fold-back during over-current and thermal shutdown protection during over-voltage or over-temperature conditions.

The NCL30060B2DR2G has multiple application fields such as industrial, medical and consumer, to name a few. In industrial applications, the device is used to provide high efficiency step-down conversion between various DC power supplies. In medical devices and applications the NCL30060B2DR2G is used in bedside monitors, diabetic glucose monitors and specialty lighting applications, where high efficiency step-down conversion between two power supplies is required.

Similarly, in consumer electronic applications, the NCL30060B2DR2G is used as a step-down DC-DC converter to power LEDs through precise control and current regulation. This makes the NCL30060B2DR2G an ideal choice for large and medium LCD displays, LED TV backlighting, external displays and other LED illumination applications.

The NCL30060B2DR2G is a versatile LED driver and is used in various applications where the precise control of output current is required. The device allows for voltage levels to be adjusted lower than the LED’s forward voltage, providing precise control and higher efficiency over the application. The NCL30060B2DR2G is a robust LED driver and offers excellent performance in terms of efficiency, stability and reliability.
