LP5521YQ/NOPB Overview


Additionally, there is a 24-VFQFN Exposed Pad package for saving space.This mounting method is Surface Mount.It emergys as a DC DC Regulator with high efficiency and reliable performance.LED drivers capable of operating at -30°C~85°C TA can be used.There are many benefits for Backlight.It operates with 24 terminations.It is configured with 24 pins as its base.It is possible for undetermined failures to occur if the voltage supply falls below 2.7V.A total of 3 segments are estimated.The mount is in the direction of Surface Mount.Under the base part number LP5521, you'll find this LED driver.As a maximum value, 5.5V is acceptable.The device has a voltage output of 4.55V volts.On it, there are 24 pins.Further, it can be classified as Display Drivers based on its characteristics.The system works with a minimum supply voltage of 2.7V in order to achieve maximum efficiency.When the maximum supply current is less than 1.5mA, the device is able to provide a high level of efficiency.Loads can only be powered by 25.5mA current.It's possible for this electronic component to fully function when the switching frequency is maintained at 1.25MHz.In the absence of external factors, there is 1.5mA consumption of current.
