NCP5006SNT1G Integrated Circuits (ICs)

NCP5006SNT1G is a high-power LED controller which belongs to PMIC - LED Drivers. LED drivers are electrical circuits which are used to control the brightness of an LED. NCP5006SNT1G has been widely adopted in a variety of applications, such as lighting and industrial illumination, display and sign building applications, including interior decoration, automotive lighting, automotive interior lighting, etc.

NCP5006SNT1G can control up to 250W of total LED load and has a low external components count - only a few external resistors are required. The device works in pulse width modulation mode at a frequency of 440 kHz and the PWM dimming range is between 0 and 100%. It has various safety protection features such as open circuit protection, over current and thermal protection. Moreover, it has high-speed switching capability and is EMI/RFI compliant.

The working principle of NCP5006SNT1G comprises two stages. The first stage is a current-mode PWM (pulse width modulation) controller whose output is used to drive a Buck-Boost converter. The Buck-Boost converter regulates the output voltage. The oscillator is driven by the integrated transconductance amplifier which is used to pulse width modulate the current. This current is used to regulate the output current at the desired level. The second stage of the NCP5006SNT1G is the Buck-Boost converter which regulates the output voltage to the desired level.

The NCP5006SNT1G is a high-power LED driver that combines a current-mode PWM controller with a Buck-Boost converter. It has various safety protection features, high-speed switching capability and is EMI/RFI compliant. The device is widely used in lighting, industrial illumination, display and sign building applications and automotive lighting due to its capability to control up to 250W LED load, low external components count and PWM dimming range of 0 to 100%.
