LM3639AYFQT

LM3639AYFQT Overview

To save board space, it uses the 20-WFBGA, DSBGA package. For the design of these LED drivers, 4 outputs are used.It is possible to mount the led driver using Surface Mount.As a DC DC Regulator, it has high efficiency and reliability.LED drivers capable of operating at -40°C~85°C TA can be used.The benefits it provides to Backlight are considerable.500kHz 4MHz is the frequency in which it operates.It is designed to work with 20 terminations.A configuration of this chip is made up of 20 pins.Undetermined failures can occur if the voltage supply is below 2.5V.The number of segments is estimated to be 16.It is mounted in the way of Surface Mount.LM3639 is the base part number for this LED driver.The supply voltage of 5.5V is an acceptable maximum value.40V is the voltage output.Additionally, it is categorized into Display Drivers according to its characteristics.As a result, it is designed to operate at a minimal voltage of 2.5V to ensure the most efficiency possible.It is possible to provide high efficiency when the maximal supply current is less than 2mA.Having the switching frequency at 500kHz enables this electronic component to perform at its best.It is currently possible to transmit over 2 channels.
