LP55271TL/NOPB Overview
In order to save board space, the 30-WFBGA package is used. It has 5 outputs for LED drivers.For mounting, it uses the Surface Mount method.With high efficiency, it emerges as a DC DC Regulator.It is possible for the led driver ic to function normally at -30°C~85°C TA.Backlight, Camera Flash has many advantages.This system operates at 1MHz~2MHz frequency.In this case, there are 30 terminations.There are 30 pins on its base.Undetermined failures may occur if the voltage supply falls below 3V.Surface Mount has been mounted with the device.The LED driver is available under the part number LP55271.There is no maximum value acceptable for the supply voltage, so 5.5V is acceptable.There is 4V~5.4V voltage output from it.As a result, it can also be classified as Display Drivers.In order to achieve highest efficiency standards, the supply voltage must be very low, preferably at 3V.It is possible to obtain a high efficiency with this device when the maximum supply current is less than 850μA.There is no current that can be supplied to the load.This electronic component can fully perform when the switching frequency is 2MHz.
