LP5521YQX/NOPB Overview

LP5521YQX/NOPB LED driver is an extremely integrated LED driver that is a common cathode that has 48 sources of constant current and 16 FETs that scan. LP5521YQX/NOPB driver utilizes a fast rising-edge transmission interface. LP5521YQX/NOPB circuit also implements LED open/weak-short/short detections and removals during operations.

The board's 24-VFQFN Exposed Pad package saves space. The mounting method is Surface Mount.As a DC DC Regulator, it has high efficiency and reliability.The led light driver operates normally at -30°C~85°C TA. As a result, Backlight is likely to benefit greatly.In this case, the termination value is 24.To form its configuration, 24 pins are used.If the voltage supply is below 2.7V, undetermined failures may occur.It is estimated that there are 3 segments.It's mounted on the way to Surface Mount.It is under the base part number LP5521 that you can find this LED driver.5.5V is an acceptable maximum value for the supply voltage.4.55V is the output voltage.This device contains 24 pins.Additionally, it can be classified as Display Drivers based on its characteristics.For highest efficiency, it works with a minimal supply voltage of 2.7V.It is capable of delivering high efficiency when the maximal supply current is below 1.5mA.This electronic component may perform its functions fully if the switching frequency is maintained at 1.25MHz.A current of 1.5mA is consumed in the absence of external influences.
