LM3463SQ/NOPB is one of Texas Instruments\' LED (Light Emitting Diode) driver integrated circuits. It is considered a PMIC (Power Management Integrated Circuit) and is designed to deliver current to LED lighting applications. It offers a wide input voltage range, excellent thermal performance, adjustable maximum current limit, over temperature protection, integrated Pulse-Width Modulation (PWM) support, and a highly efficient current source with excellent load regulation. The device also provides a wide range of features that make it suitable for a wide range of LED applications, including TV sets, laptop computers, automotive, and general purpose lighting.The LM3463SQ/NOPB is a dual-channel, high-efficiency, high-voltage, non-isolated 3W LED driver. Both channels feature a 0.6A (Max) sink capability. It has a wide 4V to 36V input voltage range, which makes it suitable for many different applications. It also features an adjustable pre-bias voltage, which allows for the pre-bias control of LEDs during normal operation.The LM3463SQ/NOPB is designed to drive LEDs from 2V up to 36V in either constant current or constant voltage modes without the need for external components. It has adjustable maximum current limit and integrated pulse-width modulation (PWM) support for dimming control. The device features an integrated over temperature protection, and provides an electronically adjustable output current for maximum brightness control in different LED applications.The LM3463SQ/NOPB works according to the pulse width modulation (PWM) technique which means that the average current through the LEDs is adjusted. By controlling the on and off times of the PWM signal, the device can have a constant current output that is put across the LEDs.A PWM signal is generated internally, which is then filtered through an external resistor-capacitor (RC) network and delivered to the LED’s. The LM3463SQ/NOPB will reduce the LED current when the LED temperature exceeds the over temperature protection limit.The LM3463SQ/NOPB design ensures excellent thermal performance. Its integrated heatsink spreads the dissipation over a large area, and its low thermal resistance to the ambient environment ensures low device temperatures. Its thermal performance is further enhanced by its small form factor and convenient mounting features.The LM3463SQ/NOPBis a versatile and highly efficient LED driver, suitable for a wide range of lighting applications. It can be used with a wide range of LEDs, and can be easily integrated into many different types of designs. Its wide range of features and its excellent thermal performance make the LM3463SQ/NOPB an ideal choice for applications that require robust and reliable LED drivers.
