LED lighting is increasingly being used across a wide range of applications, including automotive, commercial and residential, due to its high efficiency, low cost and long lifetime. This has led to the development of increasingly complex LED drivers that support increasingly high power and output levels. The LM2751SDX-A is a high efficiency PMIC – LED driver that offers excellent performance in a variety of applications.

The LM2751SDX-A is designed to provide a solution for driving multiple channels of LEDs from any input voltage up to 48V. The device offers up to 94% efficiency, and provides high power output of up to 6.4A and 5W per channel. The LM2751SDX-A uses hybrid constant current technology to ensure accurate current control regardless of the input voltage, and provides superior performance in terms of high dynamic range and low ripple current.

The LM2751SDX-A supports up to four independent channels of LED lighting, with a CCT range of up to 136 CRI. The device includes a configurable flicker mitigation feature to reduce external visible flicker, as well as a thermally protected output power stage that helps to protect against over-current, over-voltage and over-temperature conditions should they arise. The device also includes several features to help reduce energy consumption, such as a low ripple sleep state, low quiescent current and an input current limitation feature.

The LM2751SDX-A is easily configurable using a digital interface bus, and is available in a 9mm x 9mm TQFN (Thin Quad Flat No-lead) package. The device is also versatile and supports a variety of operating modes and light sequencing functions, such as dimming, strobe and smooth dim. The device has an operating temperature range of -40°C to +105°C, and is available in a variety of voltages and current levels.

The working principle of the LM2751SDX-A is based on hybrid constant current technology. This technology is used to drive a bridge with two isolated high-side and two isolated low-side transistors that deliver the regulated current to the LEDs. The hybrid constant current technology is highly efficient and is suitable for applications that demand low ripple current and high dynamic range. The device’s input voltage range is up to 48V, and the output current range is up to 6.4A.

The LM2751SDX-A has a wide range of applications in automotive, commercial, and residential lighting. The device is well suited for applications that require a low ripple sleep state, accurate current control and energy efficient operation. The LM2751SDX-A is an ideal solution for LED drivers that require high power density, high efficiency and excellent performance.
