LM3639AYFQR Overview
There is also a 20-WFBGA, DSBGA package that is used to save space on the board. In this LED driver, there are 4 outputs.Surface Mount is used to mount the led driver.Initially, it emerges as a DC DC Regulator with high efficiency and a high degree of reliability.The led light driver is capable of working normally at -40°C~85°C TA.It is clear that Backlight will benefit from the program.Using the frequency of 500kHz 4MHz, it operates.There are 20 terminations associated with it.To form its configuration, there are 20 pins.It is inevitable that there will be undetermined failures when the supply voltage is less than 2.5V.16 segments are present.There is a device mounted on the Surface Mount.The LED driver can be found under the base part number LM3639.As a maximum value, 5.5V is acceptable.The device has a voltage output of 40V volts.In addition to Display Drivers, it is also classified by its characteristics.It works with the minimal supply voltage of 2.5V to meet highest efficiency standards.As long as the supply current is less than 2mA, this device can provide high efficiency.The electronic component can function fully when the switching frequency is maintained at 500kHz.There are currently 2 channels available for transmission.
