LP8543SQX/NOPB Overview
Its 24-WFQFN Exposed Pad package is used to save board space. This LED driver has 7 outputs.To mount, use Surface Mount.In this case, it emerges as a DC DC Regulator with a high efficiency.-30°C~85°C TA is the operating temperature for the led light driver.Backlight has significant advantages.As a result, it operates on the basis of frequency 625kHz~1.25MHz.The terminations 24 are designed for its operation.This LED driver is configured with a base of 24 pins.Having a voltage supply below 5.5V can lead to undetermined failures.In total, it includes 12 segments.The device has been mounted on the Surface Mount.This LED driver has the part number LP8543.22V is a maximum acceptable voltage for the supply.There is 40V voltage output from the device.Moreover, it can be classified as Display Drivers due to its characteristics.The system operates at a minimum supply voltage of 5.5V in order to achieve maximum efficiency.When the supply current should be less than 3.5mA, the device will provide high efficiency.
