LM3431AMH/NOPB Overview
To save board space, it uses the 28-PowerTSSOP (0.173, 4.40mm Width) package. In LED drivers, the outputs are all set to 3.It adopts the way of Surface Mount for mounting.With high efficiency and reliable performance, it emerges as a DC DC Controller.It is able to work normally at the operating temperature of -40°C~125°C TJ.A number of benefits are available to Backlight.The LED light driver is configured with a base of 0 pins.Undetermined failures can occur if the voltage supply is below 4.5V.The device has been mounted on the Surface Mount.This LED driver has the part number LM3431.Ideally, the supply voltage should be 36V.In order to achieve highest efficiency standards, the supply voltage must be very low, preferably at 4.5V.When the maximum supply current is less than 4.85mA, this device is able to provide high efficiency.There is no current available to supply to the load.This electronic component can fully perform when the switching frequency is 1MHz.The consumption of current is 4mAin the absence of external factors.This device produces a voltage of 40V as its output.
