LP55231SQX/NOPB Overview

The 24-WFQFN Exposed Pad package is used for saving board space. Mounting is done according to the Surface Mount method.It is highly reliable and high-performing when it emerges as a DC DC Regulator.-30°C~85°C TA is the operating temperature and it works fine.Backlight has considerable advantages.24 terminations are used in its operation.To form its configuration, there are 24 pins.A total of 9 segments have been created.Surface Mount is mounted in the way.LP55231 is the base part number for this LED driver.The voltage of 5.5V is acceptable.According to its characteristics, it is also categorized into Display Drivers.With 2.7V as the minimal input voltage, it operates.This system is designed to operate at a minimum voltage of 2.7V to achieve maximum efficiency.In the case of supply current, there is a maximum value of 5.5V.With a minimum supply current less than 750μA, this device achieves high efficiency.There is no current available to supply to the load.Having the switching frequency at 1.25MHz enables this electronic component to perform at its best.At maximum output current 25.5mA, it will deliver all the benefits of a LED driver.In the absence of external factors, there is 800μA consumption of current.Voltages should not exceed 5.5V volts at the output.It maintains a minimum voltage of 3.6V.
