LM3463EVM is a highly integrated versatile AC/DC dimmable LED driver that provides advanced control of power and current in side-by-side driver applications. Its wide output current and voltage range of 3A/24V and its power-saving feature set make it an ideal solution for driving multiple strings of LEDs for general illumination and other non-residential applications.The LM3463EVM is a powerful and versatile dimmable LED driver. It provides an efficient, cost-effective solution for controlling multiple strings of LEDs simultaneously. Designed for general illumination applications, the driver offers a compact package and a wide output current and voltage range of 3A/24V. In addition, the device features comprehensive control logic to enable the delivery of both constant and pulse current modulation dimming with PWM, dim-to-off, and linear dimming control interfaces. For those applications utilizing a separate AC/DC power supply, the driver includes an integrated high-voltage AC/DC controller as well as protection features that detect and respond to power supply faults.The LM3463EVM driver is ideal for side-by-side LED applications using multiple strings of LEDs. Using its power-saving features, the driver can maximize efficiency and reduce power consumption to help reduce cost. The built-in comprehensive control logic offers fine granularity of power control and dimmer options. The linear dimming capabilities allow for smooth and flicker-free LED dimming control, while the pulse current modulation dimming feature allows for high-pulse frequencies to be used for high-power LED strings.The LM3463EVM offers a wide range of operational features that provide a high degree of versatility and performance. The device can operate from wide AC input voltage range of 90 to 305 V AC. It also supports 12/24V DC input voltage range and its output can be set for constant current output up to 3A and for constant voltage output up to 24V. The power-saving features of the device include an adaptive dimming control circuit which can reduce the string current at light levels below maximum to reduce power consumption. It also offers integrated over-voltage and under-voltage protection and provide warning signals when either of the conditions occur.The working principle of the LM3463EVM driver is based on a combination of power-saving features, advanced control logic and a high-voltage AC/DC controller. It operates using a unique dimming algorithm that combines pulse current modulation with linear dimming. This algorithm is based on a dimmer input that ranges from 0 to 10 VDC. When the dimmer input is set at 0 VDC, the current to the LEDs is disabled, and when it is set above max voltage, the LEDs are fully lit.When the dimmer input is between 0 and max voltage, the pulse current modulation dimming algorithm is executed. This allows for varying the drive current to the LEDs according to the desired light level, resulting in a smooth, flicker-free dimming effect. In addition, the LM3463EVM incorporates advanced control logic so that the dimmer input can be routed to multiple LED drivers, allowing for flexible control of multiple LED strings simultaneously.In conclusion, the LM3463EVM is a powerful and versatile dimmable LED driver. It offers an efficient, cost-effective solution for controlling multiple strings of LEDs simultaneously. Its wide output current and voltage range make it an ideal solution for driving multiple strings of LEDs for general illumination and other non-residential applications. With its power-saving features, advanced control logic, and high-voltage AC/DC controller, it is an ideal choice for both residential and commercial LED lighting applications.
