The integrated state machine that provides a superb dimming and strobe capability and extremely small board size. In addition, it also has over voltage protection and Soft-Start for Light Emitting Diode (LED) applications. The low output ripple and low conduction loss make it an ideal solution for driving LEDs when used in an array. The LXV40-036SW is designed to be lightweight, highly reliable and long lasting.

Working Principle

The LXV40-036SW is a typical topology used for LED drivers, which is a buck controller. It is a switch mode power supply that converts the input voltage to the LED\'s required voltage and current. The switch mode normally only requires two main components, the power MOSFET switches and the control circuitry. The basic principles are to generate a linear analog control signal which represents the LED voltage light output and a rapid pulsing signal to switch the MOSFET gate in order to deliver the desired output.

The LXV40-036SW LED Driver is a DC-DC controller with regulated current output and voltage output protection. Its internal PWM signal generates the drive for the power MOSFET switches which control the output voltage. This voltage feedback system senses the amount of current flowing through the LED and adjusts the duty cycle of the PWM signal accordingly. The input voltage passes through the MOSFET switch and is then rectified by the rectifier diode. After the current is limited by having the sense resistor and smoothing capacitor, the current is then passed to the LED load. The voltage across the LED then goes into the current loop and this loop then regulates the amount of voltage drop across the sense resistor.

Application

The LXV40-036SW is well suited for driving a wide range of 3V-36V LED applications, such as LED strips, LED lamps, outdoor lighting, and automotive lighting. It is ideal for portable lighting requirements, such as bike lights, USB-powered accessories, camping lights, and battery-powered lighting. In addition, it is also useful for low-power lighting applications, such as LED lights, LED flashlights, LED signs, and LED displays.

The LXV40-036SW is well-suited for lighting applications requiring stable voltage, high efficiency, and efficient thermal management. The low ripple voltage and wide input voltage range make it an ideal choice for applications that require a long life. The Soft-Start feature helps ensure that the LED drivers won’t be damaged and the integrated state machine allows for dimming capability and excellent control features. The small package size makes it easy to install into existing lighting fixtures and it is highly reliable.
