LED Drivers are the components used in lighting systems to convert the electrical power input into controllable electrical power for LEDs. LED drivers often provide solutions with a built-in controller, over-temperature protection and power regulation. The LXV75-105SW is one such solution that is used in a range of applications.

The LXV75-105SW LED Driver is a fully integrated, ultra-low-power, continuous mode LED driver solution that is ideal for use in portable devices such as smart phones, tablet PCs, laptops, and monitors. It supports a wide range of LED levels from 20mA to 200mA, and operates from an input voltage of 2.7V to 5.5V. It is designed to offer ultra-long battery life with no LED flicker and very low quiescent current. The LXV75-105SW also offers a wide range of programmable features, such as a dimmable output current, dimming mode selector, adjustable dimming curves, and programmable current foldback.

The LXV75-105SW LED Driver is primarily used in portable devices for display backlighting and secondary LED illumination applications. The device can also be used in outdoor applications such as street lights, traffic lights, and flood lighting. The LXV75-105SW LED Driver is suitable for use in automotive applications, such as interior and glove-box lighting, instrument cluster backlighting, and vehicle exterior lighting. Additionally, the device can be used in home and small office appliance applications, such as washing machine monitors, coffee makers, and security cameras.

The LXV75-105SW LED Driver operates on the principle of current regulation. It uses a control loop circuit to regulate the current flow through the LED string. The device features an internal voltage reference, which is used to set the maximum current to be allowed through the LED string. The output current is proportional to the control signal applied to the control pin, with a maximum output current equal to the set maximum current. The device also features a foldback feature, which reduces the LM331 output current when the LED junction temperature reaches a certain threshold.

The LXV75-105SW LED Driver is designed to offer high efficiency and low power consumption. The device has a wide operating temperature range of -40°C to +85°C and is protected against overtemperature conditions. The device is designed to meet the requirements of the EN 55020: 2011 specification for radiated and conducted EMC compliance. The LXV75-105SW LED Driver is available in two package options, an 8-pin SOIC or a 9-pin Wafer level package, and is RoHS compliant.
