The LM2726MX is an integrated circuit (IC) component primarily designed for driving white light emitting diodes (LEDs) in backlight applications of large LCD panels. It offers various key features that aid in controlling the LED current and hence, ensuring optimal performance.
One of the essential features of the LM2726MX is its ability to provide a constant current source for driving LEDs. It incorporates a built-in current-mode boost converter that regulates the LED current accurately, ensuring consistent brightness and uniformity across multiple LEDs. The IC utilizes a high switching frequency to drive small-sized inductors, resulting in overall application size reduction.
To enhance its LED driving capabilities, the LM2726MX incorporates an internal high-voltage power MOSFET. This feature eliminates the need for an external MOSFET, minimizing the overall bill of materials, reducing component count, and simplifying the design process. Additionally, the IC includes an adjustable peak current limit that allows precise control over the LED current, protecting them from overloading and potential damage.
The LM2726MX provides flexible dimming control options. It supports both analog and pulse-width modulation (PWM) dimming techniques, allowing users to adjust the LED brightness according to their requirements. The IC includes dedicated pins for analog dimming control, facilitating integration with external control systems. Moreover, the LM2726MX offers a wide dimming range, enabling smooth brightness adjustments.
Another key feature of the LM2726MX is its comprehensive fault protection mechanism
