LED Drivers
MLV3C70 is a LED driver, it uses a digital pulse-width (PWM) modulation drive technology, suitable for voltage and current regulated driving applications. It provides high efficiency, low power consumption, stable performance and a wide range of control applications for LED clusters.
Application Field
MLV3C70 can be used in a variety of scenarios such as general lighting, automotive lighting, decorative lighting, backlight for LCD/LED/OLED panels, stage lighting and projection systems, LED signage, medical lighting, military lighting, emergency lighting and other industrial applications.
Working Principle
At its simplest, MLV3C70 uses two digitally controlled MOSFET switches and a decoding circuit to modulate LED output brightness. The output of the driver is controlled by a charging and discharging process. When two switching MOS transistors (one for charging, one for discharging) are switched on, current will flow through the coil. Initially the current will be zero but as current builds up in the coil, the current will start to flow through the LED, thus illumination. With the use of a pulse-width modulation signal, the switching time of the two MOSFET can be controlled. This is what controls the LED as the pulse-width of the signal is the main parameter determining the output brightness of the LED.
In this way, both the voltage and current of the LED can be regulated with the MLV3C70. The voltage of the LED can be adjusted by adjusting the voltage across the coil, and the current of the LED can be adjusted by changing the pulse-width of the signal. As a result, a wide range of LED outputs can be achieved.
