The LM3630ATMX is a very versatile full featured LED driver that offers a large range of options for controlling and driving LEDs. The LM3630ATMX is designed for use with high-brightness LEDs and can be used to drive up to 8 channels of LED strings with multiple LED types such as light-emitting diodes (LEDs), organic LEDs (OLEDs), and fluorescent lamps. The LM3630ATMX also features several control modes including pulse width modulation (PWM) and color temperature (CT) as well as a digital dimming interface.

The LM3630ATMX is used to drive high-brightness LEDs in a range of applications, including both residential and commercial lighting, automotive, and various industrial applications. It is especially useful for providing low-voltage capability for powering high-power LEDs or for providing a range of pulse width modulation (PWM) dimming modes. It can also be used for controlling RGB LED displays, and for simplified dimming applications when combined with analog switches.

Working Principle

The LM3630ATMX works by providing the necessary voltage and current to drive the LEDs. It works by first converting the incoming voltage to a voltage that is suitable for the LEDs. This is then used to drive the LEDs and the LM3630ATMX can be controlled using one of several methods. The most common methods used are pulse width modulation (PWM) and direct digital control (DDC).

Pulse width modulation (PWM) is an efficient way to control the power output of the LED. It works by controlling the ‘on’ and ‘off’ times of the LED, so that the brightness is a function of how long the LED is ‘on’ compared to how long it is ‘off’. This can be controlled via a PWM pin on the LM3630ATMX, and the frequency can be programmed to a wide range of values.

The Direct Digital Control (DDC) feature of the LM3630ATMX works by controlling the voltage and current supplied to the LEDs directly, rather than by curve-tracing or pulse-width modulation PWM. The LM3630ATMX is therefore able to produce a wide range of effects without the need for complex programming and calculations. For example, it can be used to provide a constant current level to the LEDs, or to create a linear, square or sine wave dimming effect.

The LM3630ATMX also includes various pre-programmed color temperature functions, which allow it to be used to create multi-channel dimming effects, such as fading, strobing, and color temperature control.

The LM3630ATMX is an excellent choice for driving LEDs in a range of different applications. It has a wide range of options for controlling and dimming LEDs, and is able to provide a smooth, linear dimming effect with minimal effort. The DDC feature makes it ideal for applications that require complex control and effects, without the need for complex programming or calculations. The LM3630ATMX is available in both DIP and SMD packages and is a versatile and cost effective LED driver for a variety of different applications.
