S-1000N20-N4T1G Application Field and Working Principle
The S-1000N20-N4T1G, produced by RADIANT LED, is a high-performance Multi-Channel Constant-Current LED Driver integrated circuit that is used in LED back light and LED stroboscopic lighting.
The S-1000N20-N4T1G is a full bridge, four-channel, constant-current LED driver. It features low power operation, low EMI (<2.5μF), wide range of driver current (0.8A to 4.5A), and fast transient response (1μs). The LED driver has built-in microcontroller, gate driver and power MOSFET. It also can be programmed with a serial interface.
The S-1000N20-N4T1G can be applied in the LCD back light market and lighting applications, such as RGB LED display, linear LED illumination, and LED security lighting. It is also suitable for a range of different applications, such as automotive, consumer, industrial, and medical.
The S-1000N20-N4T1G can be used in three different configurations. In one configuration, the S-1000N20-N4T1G operates as a multi-channel current source and can be used to drive multiple LEDs in series or in parallel. In the second configuration, the S-1000N20-N4T1G operates as a single current source and can be used to drive a single LED in series or in parallel. In the third configuration, the S-1000N20-N4T1G can be used in a PWM dimming mode to drive a single LED in series or in parallel.
Working Principle
The S-1000N20-N4T1G operates in two major modes, constant-current (CC) and PWM dimming. In CC mode, the LED driver regulates the LED current by using a sophisticated current regulator based on a current feedback loop. The LED current can be adjusted by setting a digital reference current. In PWM dimming mode, the output of the gate driver can be modulated by applying a PWM signal. The duty cycle of the PWM signal determines the LED brightness.
The S-1000N20-N4T1G also provides a variety of protection functions, such as temperature protection, over-temperature protection, over-voltage protection, reverse current protection, and over-current protection. It also offers a wide range of protections for the LEDs, such as short-circuit protection and over-drive protection.
The S-1000N20-N4T1G is versatile and offers flexibilty in application. It is a perfect solution for powering and dimming multiple LEDs with high efficiency and precision.
